RVP0.S10 VALVE SERIES
SAE Cartridge - 420 bar
Pilot Operated with anti-cavitation
Poppet type
DESCRIPTION
The RVP valve combines in one compact cartridge the typical function of relief valve and anticavitation through the check valve. It’s
a screw-in, pilot operated (2-stage), poppet type, normally closed valve. When the pressure at the Inlet (1) reaches the valve
setting, the pilot poppet starts to open from its seat and determines the shifting of the main stage poppet that throttles oil flow to tank
(2). In the free reverse flow function a light bias spring allows for ease of flow passage from side to nose (2 to 1). The cartridge
offers smooth transition in response to load changes in demanding hydraulic circuits. Smooth response, reduced pressure rise and
limited hysteresis.
