The reference force element is usually a mechanical spring. Material Chrome-Plated Brass Body
It is compact and light-weighted. Custom designs are available upon request.
This spring exerts a force on the sensing element and acts to open the valve.
Then, again, gradually increase the pressure to the desired set point.
NOTE: Avoid turning the adjustment screw all the way into the regulator because, in some regulator designs, the full supply pressure will be delivered to the outlet port. If you overshoot the set point while setting the pressure regulator, back off the set pressure to a point below the set point. For special applications / configurations give us your operational parameters and well build it to meet your needs.
Examples include portable analytical instruments, hydrogen fuel cells, UAVs, and medical devices powered by high pressure gas supplied from a gas cartridge or storage cylinder. The pre-set regulator provides a stable pressure point, even when the inlet pressure fluctuates. Typically there is a vent hole in the side of the regulator body for this purpose.
In high flow rate applications, icing of the regulator can occur if moisture is present.
Springs used inside the regulator are typically made of music wire (carbon steel) or stainless steel.
Diaphragm regulators employ a thin disc shaped element which is used to sense pressure changes. Most manufacturers recommend the installation of a filter upstream of the regulator (some regulators have a built-in filter) to prevent dirt and particulates from contaminating the valve seat. Shock proof. The presence of oil in the gas is often not apparent to the user and therefore this topic should be discussed with your gas supplier before you select the seal materials for your regulator.
PISCO offers new pressure reducing valve.
Equally important is the compatibility of the seal material with the fluid and with the operating temperature range.

The opening of the valve applies pressure to the sensing element which in turn closes the valve until it is open just enough to maintain the set pressure.
Various grades of stainless steel (such as 303, 304, and 316) are available too. When selecting a regulator, engineers should examine pressure versus flow curves to ensure the regulator can meet the performance requirements necessary for the proposed application. A non-relieving regulator is preferred for use with hazardous, explosive, or expensive gases because the design does not vent excessive downstream pressure into the atmosphere.
Many users are unaware that gases supplied in cylinders and small gas cartridges can contain traces of oils from the manufacturing process. If this type of design is selected the excess fluid should be vented appropriately and in accordance to all safety regulations.
Available inseveral different models to cover numerous applications and setups . Material selection, particularly the regulator body components, will impact weight. Pressure regulators reduce a supply (or inlet) pressure to a lower outlet pressure and work to maintain this outlet pressure despite fluctuations in the inlet pressure.
It is also important to determine if the fluid is flammable, toxic, explosive, or hazardous in nature. The pressure versus flow curves provided in the graph Direct Acting Pressure Regulator Operating Map, indicates the useful regulating capacity of the regulator. For more information, go to www.P65Warnings.ca.gov.
Lockup pressure is the pressure above the set-point that is required to completely shut the regulator valve off and insure that there is no flow. 90 Inline Stabilizer, Co2 Air Pneumatic Regulator Up to 4500 psi input. Optional seals are offered by some manufacturers and these include: Fluorocarbon, EPDM, Silicone, and Perfluoroelastomer. A regulator with an oversized valve, for the conditions of the intended application, will result in a greater sensitivity to fluctuating inlet pressures, and may cause excessive droop. The long proven performance of Palmer's Regulators, makesthem a must for all pressure controlled systems. In contrast to a non-relieving regulator, a relieving (also known as self-relieving) regulator is designed to vent excess downstream pressure to atmosphere. STEP 4To obtain the desired outlet pressure, make the final adjustments by slowly increasing the pressure from below the desired set point. This may be beneficial if your design can accommodate a bigger regulator however be careful not to over specify.
Brass is suited to most common applications and is usually economical. Often this is a spring loaded poppet valve. )
The poppet includes an elastomeric seal or, in some high pressure designs a thermoplastic seal, which is configured to make a seal on a valve seat.
Porting requirements are also an important consideration.
As seen in the graph Direct Acting Pressure Regulator Operating Map, this effect is important to a user because it shows the useful regulating capacity of a regulator.
STEP 2Before turning on the supply pressure to the regulator, back off the adjustment control knob to restrict flow through the regulator. Additionally, the operating temperature may affect flow capacity and/or the spring rate in extreme applications.
(see below).
The pressure setting is factory set and cannot be changed or adjusted, which provides operators safe and continuous performance.
As the inlet pressure rises from the initial setting, the outlet pressure falls.

Gauge Diameters 2 inch
For example, the air compressors used in most factories generate maximum pressures in the 100 to 150 psi range. In many high technology applications space is limited and weight is a factor.
STEP 5Cycle the supply pressure on and off several times while monitoring the outlet pressure to confirm the regulator is consistently returning to the set point. Pressure Regulators are found in many common home and industrial applications. Droop can also be caused by significant changes in the inlet pressure (from the value when the regulator output was set). $ 131.32, Female Stabilizer Co2 Air Pneumatic Regulator Up to 4500 psi input Adjustable 200 - 900 psi output, Input: Female .825x14 NGO threads, Inline Stabilizer, Co2 Air Pneumatic Regulator Up to 4500 psi input Adjustable 200-900 psi output.
If the regulator in non-relieving, it will be easier to adjust the outlet pressure if fluid is flowing rather than dead ended (no flow).
Increasing the valve orifice can increase the flow capacity of the regulator. What is the required outlet pressure?
Never vent fluid by loosening fittings, as injury may result.
more information Accept.
Setting the pressure from below the desired setting is preferred to setting it from above the desired setting. The Stabilizer is shipped with a factory test setting of 500 psi. The chemical properties of the fluid should be considered before determining the best materials for your application.
Some manufactures specialize in miniature components and should be consulted.
The Western M1-950-PGB Medical Air Adjustable Pressure Regulator has a 0-50 PSI capacity. In a two-stage design the second stage will not be subjected to these large changes in inlet pressure, only the slight change from the outlet of the first stage. Pressure regulators are not intended to be used as shutoff devices.
With most single-stage regulator regulators, except those that use a pressure compensated design, a large drop in inlet pressure will cause a slight increase in outlet pressure. STEP 1Begin by connecting the pressure source to the inlet port and the regulated pressure line to the outlet port.
How much does the flow rate vary?
The regulator has an all brass body and high pressure chamber. This happens because the forces acting on the valve change, due to the large drop in pressure, from when the outlet pressure was initially set.
$ 210.00, Sideline Stabilizer Co2 Air Pneumatic Regulator up to 4500 psi input Adjustable 200-900 psi output. In low pressure applications, or when high accuracy is required, the diaphragm style is preferred. Additionally, for a particular regulator size, it is often possible to provide a greater sensing area with a diaphragm design than would be feasible if a piston style design was employed. Male Stabilizer Co2 Air Pneumatic Regulator Up to 4500 psi input Adjustable 0-700 psi output.
For example, the Beswick PRD3HP series three-stage regulator is rated to handle an inlet pressure as high as 3,000 psi and it will provide a stable outlet pressure (in the 0 to 30 psi range) despite changes to the supply pressure.
Regulated gases should be free from oils, greases, and other contaminants which could foul or damage the valve components or attack the regulator seals.
Medical Air Single Stage 0-50 Adjustable Pressure Clinical Regulator The parts of the regulator in contact with the fluid are known as the wetted components. As this partial list demonstrates there are numerous applications for regulators yet, in each of them, the pressure regulator provides the same function.

Do not connect regulators to a supply source with a maximum pressure greater than the rated inlet pressure of the regulator.
Stainless Steels are often chosen for use with corrosive fluids, use in corrosive environments, when cleanliness of the fluid is a consideration or when the operating temperatures will be high.
What they didnt teach you about fittings in engineering school! ) Plastic is considered when low cost is of primarily concern or a throw away item is required. When the downstream pressure drops below the set-point, the spring pushes the poppet away from the valve seat and additional fluid is allowed to flow from the inlet to the outlet until the force balance is restored. Most commonly a spring. The materials selected for the pressure regulator not only need to be compatible with the fluid but also must be able to function properly at the expected operating temperature.
Single stage pressure regulators typically do not perform well with large swings in inlet pressure and/or flow rates.
Submit your inquiry on ourContact Uspage or click the Live Chat icon in the bottom right of your screen. Aluminum is often specified when weight is a consideration. The factory pressure set is from 0.2 to 0.6MPa (29 to 87psi), every 0.05MPa (every 7psi), Flow Control, Needle, Quick Exhaust Valves, Silencer / Muffler / Exhaust Needle Valve, Check Valves / Back Flow Preventing Valves, Solenoid Valves / Directional Control Valves, Grippers / Actuators / EOAT (End of Arm Tooling), Vacuum Generators (Multi-Task / Manifold Solenoid), Vacuum Pumps / Vacuum Controller / Air Tank, Pre-set (Tamper-Proof) In-Line Pressure Regulator. Most regulators are designed with an adjustment which allows the user to adjust the outlet pressure set-point by changing the force exerted by the reference spring. A small and lightweight pressure regulator that can maintain a stable low output pressure despite an inlet pressure that will decrease over time from a high pressure is a critical component in many designs. Single-stage regulators are an excellent choice for relatively small reductions in pressure.
Beswick Engineering specializes in miniature liquid and pneumatic fittings, quick disconnects, valves and regulators. Male Stabilizer Co2 Air Pneumatic Regulator Up to 4500 psi input Adjustable 200-900 psi output. Most commonly, regulators employ a spring loaded poppet valve as a restrictive element.

Durable neoprene diaphragm
Piston designs tend to be sluggish, as compared to diaphragm designs, because of the friction between the piston seal and the regulator body.
to operate automated machinery, test stands, machine tools, leak test equipment, linear actuators, and other devices. Repeat the pressure setting sequence if the outlet pressure does not return to the desired setting. Additionally, gasses should be free of excessive moisture. 0-50 PSI
Also carefully consider the port (thread) sizes, adjustment styles, and mounting options as these will influence size and weight. Industrial, NASA, scientific, medical and custom applications available. With a relieving style regulator, excess pressure will be automatically vented to atmosphere from the downstream side of the regulator when the knob is rotated to lower the output setting. Sintered filter for additional safety and to extend regulator life, By continuing to use the site, you agree to the use of cookies. When choosing a pressure regulator many factors must be considered. Important considerations include: operating pressure ranges for the inlet and outlet, flow requirements, the fluid (Is it a gas, a liquid, toxic, or flammable?
We have a team of degreed Application Engineers ready to assist you with your questions.
They are usually made of an elastomer, however, thin convoluted metal is used in special applications.
A reverse flow mechanism allows installation between solenoid valves and cylinders.
Operation of a regulator without a filter could result in a leaking to the outlet port if the valve seat is contaminated with dirt or foreign material. Internal reseating relief valve protects against over-pressurization In some designs, damage can occur to the internal components if the supply pressure is mistakenly supplied to the outlet port. Be sure the excess fluid is vented safely and in accordance with all local, state and federal regulations.
The cookie settings on this website are set to "allow cookies" to give you the best browsing experience possible.
The inlet and outlet pressures are important factors to consider before choosing the best regulator.
The resulting graph shows the drop in outlet pressure as the flow rate increases.
You can find Beswicks available pressure regulators in our online catalog:Click Here for Pressure Regulators. Works in any position, upside down or even in zero gravity.
Make certain that you inform your regulator supplier that you plan to use the regulator in an oxygen application.
A wide range of materials are available to handle various fluids and operating environments. The primary concern is whether or not the elastomer chosen will function properly throughout the expected temperature range. Gradually turn on the supply pressure so as not to shock the regulator with a sudden rush of pressurized fluid.
Additionally, the outlet pressure should also be cycled on and off to ensure the pressure regulator returns to the desired set point.
When the spring force moves the seal away from the valve seat, fluid is allowed to flow from the inlet of the regulator to the outlet. Diaphragms essentially eliminate the friction inherent with piston style designs.
Input: 1/8" npt male disconnect nipple, Universal O ring Seal Kit for Rock & Stabilizer Regulator, Camille, The First Functional Semi Automatic Gravity Fed Paintball Gun by Glenn Palmer. What is the maximum flow rate that the application requires? The reduction of the inlet pressure to a lower outlet pressure is the key characteristic of pressure regulators. Important questions to answer are: What is the range of fluctuation in the inlet pressure? A pressure regulator is comprised of three functional elements, In operation, the reference force generated by the spring opens the valve. A reference force element.
Take a look at the graph and you will notice, for a given flow rate, that the outlet pressure will be higher with decreasing flow than it will be with increasing flow. These two forces reach a balance point at the set point of the pressure regulator.
Hysteresis can occur in mechanical systems, such as pressure regulators, due to friction forces caused by springs and seals. Buna-n is a typical seal material. STEP 3Set the pressure regulator to the desired outlet pressure.
A sensing element. Typically a diaphragm or piston. ) The term droop is used to describe the drop in the outlet pressure, below the original set-point, as flow increases. Now that you have chosen the regulator that best suits your application it is important that the regulator is installed and adjusted properly to insure that it functions as intended. The simplified schematic Pressure Regulator Schematic illustrates this force balance arrangement. When the regulator is not in use, the supply pressure should be turned off.
A three-stage regulator provides a stable outlet pressure similar to a two-stage regulator but with the added ability to handle a significantly higher maximum inlet pressure.
For example, pressure regulators are used in gas grills to regulate propane, in home heating furnaces to regulate natural gases, in medical and dental equipment to regulate oxygen and anesthesia gases, in pneumatic automation systems to regulate compressed air, in engines to regulate fuel and in fuel cells to regulate hydrogen.
A two-stage pressure regulator is ideal for applications with large variations in the flow rate, significant fluctuations in the inlet pressure, or decreasing inlet pressure such as occurs with gas supplied from a small storage tank or gas cylinder.
This arrangement results in a stable outlet pressure from the second stage despite the significant changes in pressure supplied to the first stage.
If the ports are not marked, check with the manufacturer to avoid incorrect connections. In some special designs, the vent port can be threaded and any excess pressure can be vented from the regulator body through tubing and exhausted in a safe area.
Max Inlet Pressure 3000 psi
Conversely, as the inlet pressure falls, the outlet pressure rises.
A 3/16 allen wrench is used to adjust pressure. If the pressure regulator will be used with oxygen, be aware that that oxygen requires specialized knowledge for safe system design.
As the outlet pressure rises, the force generated by the sensing element resists the force of the spring and the valve is closed. This phenomenon is known as droop. Input: Male 1/8 NPT threads.
For this reason, do not use relieving style regulators with flammable or hazardous fluids.
Pressure regulator accuracy is defined as how much droop the device exhibits over a range of flows; less droop equals greater accuracy. If you continue to use this website without changing your cookie settings or you click "Accept" below then you are consenting to this. Piston style designs are often used when higher outlet pressures are required, when ruggedness is a concern or when the outlet pressure does not have to be held to a tight tolerance. This pressure is piped through the factory but is often reduced with a single-stage regulator to lower pressures (10 psi, 50 psi, 80 psi etc.) What is the allowable variation in outlet pressure?
