Pilot operated slenoid relief valves_1

PB type valve is a pilot-operated relief valve. PBW type is a pilot-operated flow control solenoid relief valve which is widely used to control the pressure in hydraulic system, it can be used to unload the pressure inhydraulic systems at any time.
The performances of 5X series are better than 30 series. The 5X series can control the pressure in hydraulic systems smoothly in a wide range. This type is available for installing in a hydraulic system which demands high flow rate.
