Proportional Pressure Reducing Valve series SDRVSA

Pressure [bar]


Flow rate [l/min]


Proportional Pressure Reducing Valve series SDRVSA  are high performance, electrically operated proportional 3-way pressure reducing valves. The main components of the valves are a sandwich body (stack-mounting body) and the screw-in cartridge (type DRVSA-7P…-10…). The pressure reducing cartridges have a seated pilot stage, and the main stage is designed on the sliding spool principle. Two models are available, one with the function in P and the other with the function A and an integral bypass check valve. Both models are provided with external pilot-oil drain through Y. These valves re duce the pressure in the secondary side of P or A (for flow IN) respectively to a level that is proportional to the solenoid current, which depends on the demand signal to the electro nics. These 3-way pressure-reducing cartridges function as full-flow pressure-relief valves from port P →T or A →T re spectively as soon as the reduced pressure rises above the valve pressure setting. Thanks to the external pilot-oil drain, the reduced pressure is unaffected by any pressure fluctua tions. A pressure-gauge port M (G1/4”) is also provided in the secondary circuit.
