Take command of your pneumatic systems with our high-performance pressure regulators. Engineered to deliver stable and accurate downstream pressure, our regulators protect your equipment from overpressure, ensure consistent operation, and help optimize energy consumption for a more efficient and reliable workflow.
Maintains consistent downstream pressure regardless of inlet pressure fluctuations, ensuring reliable equipment operation.
Prevents damage to sensitive pneumatic components by protecting them from excessive supply pressure.
Allows you to set the optimal pressure for each application, reducing unnecessary air consumption and energy costs.
A pressure regulator is a valve that automatically cuts off the flow of a liquid or gas at a certain pressure. It reduces a higher inlet pressure to a lower, controlled outlet pressure and maintains this outlet pressure despite fluctuations in the inlet pressure or downstream flow demand (within its operating limits).
Responsive diaphragm/piston designs ensure precise pressure control and quick reaction to changes in flow or supply pressure.
Efficiently vents excess downstream pressure to maintain the setpoint, protecting sensitive equipment (for relieving types).
Made with high-quality body materials (e.g., aluminum alloy, brass) and wear-resistant seals for long service life.
User-friendly adjustment knobs (often with locking feature) and standard porting for simple installation and setup.
E.g., G1/8, G1/4, G3/8, G1/2, G1, NPT options.
The adjustable output pressure range (e.g., 0.05-0.85 MPa, 0.5-12 bar).
The highest supply pressure the regulator can safely handle.
Rated airflow at a specified inlet and outlet pressure (L/min, SCFM).
Whether the regulator can vent excess downstream pressure.
Availability of ports for pressure gauge installation (inlet/outlet).
Aluminum alloy, brass, stainless steel, etc.
Suitable ambient and media temperature range.

Always de-pressurize the system before performing any maintenance on pressure regulators.
The primary function of a pneumatic pressure regulator is to reduce a higher, often fluctuating, inlet air pressure to a lower, constant, and usable outlet pressure. It then maintains this set outlet pressure despite variations in the inlet pressure (as long as it’s higher than the setpoint) or changes in downstream air demand.
Relieving Regulator: This type of regulator can vent excess downstream pressure to the atmosphere if it rises above the set pressure. For example, if a cylinder retracts and pushes air back, or if ambient temperature increases causing pressure rise in a closed volume, a relieving regulator will release this excess pressure to maintain the setpoint. This is the most common type for general pneumatic applications.
Non-Relieving Regulator: This type does not have an internal mechanism to vent excess downstream pressure. If downstream pressure increases above the setpoint, it will remain trapped until consumed by the application or manually vented. Non-relieving regulators are used in applications where venting to the atmosphere is undesirable (e.g., when using specific gases other than air, or to prevent contaminants from entering the vent port).
Most regulators have an adjustment knob or screw. To set the pressure:
Always set the pressure to the minimum required by the application for optimal efficiency and component life.
A standard pressure regulator is designed to reduce pressure. If the inlet (supply) pressure drops below the set outlet pressure, the regulator will essentially become fully open, and the outlet pressure will be approximately equal to the (now lower) inlet pressure, minus any small internal pressure drop across the valve.
The regulator cannot boost or increase pressure; for that, you would need a pressure booster or a higher supply pressure.
Pressure fluctuation or “creep” (a slow rise in outlet pressure above the setpoint, especially under no-flow conditions) can be due to several reasons:
This often indicates the regulator needs cleaning, servicing (seal replacement), or replacement.
