Pressure-Regulating Inline Hydraulic Valves

When input pressure varies, use these valves to maintain a consistent pressure. They are often placed after a directional-control valve and before an actuator, such as a cylinder. They have an indicator/gauge port for the inlet and one for the outlet so you can monitor that output pressure remains steady.

Hydraulic Pressure-Relief Valves


Iron	316 Stainless Steel

To set the pressure, unscrew the cap and turn the adjustment screw. Valves begin opening at the set pressure and fully open at about 10% over the set pressure. They begin closing as pressure drops and close when the system pressure is restored below the set pressure.

Iron Body—Iron valves absorb vibration to reduce noise and wear in the pipeline.

316 Stainless Steel Body—316 stainless steel valves are more corrosion resistant than iron valves.

Easy-Adjust Hydraulic Pressure-Relief Valves


Brass	303 Stainless Steel

An external nut lets you adjust the pressure without disassembling the valve. These valves begin opening at the set pressure and fully open at about 10% over the set pressure. They begin closing as pressure drops and fully close when the system pressure is restored below the set pressure.

Brass Body—Brass valves have good corrosion resistance.

303 Stainless Steel Body—303 stainless steel valves are more corrosion resistant than brass valves.

Made-to-Order Pressure-Relief Valves

Design a valve specifically for your process media and set pressure. Choose from a valve for air, inert gas, water, hydraulic oil, fuel oil, gasoline, or diesel fuel and a set pressure. These valves begin opening at the set pressure and fully open at about 10% over the set pressure. They begin closing as pressure drops and fully close when the system pressure is restored below the set pressure. Body is 316 stainless steel for exceptional corrosion resistance.

Tamper-Resistant Hydraulic Pressure-Relief Valves

The pressure setting on these valves cannot be adjusted while they are installed. Use a hex key to unlock the locknut and turn the adjustment screw to set the pressure. Valves begin opening at the set pressure and fully open at about 10% over the set pressure. They begin closing as pressure drops and fully close when the system pressure is restored below the set pressure.
