VIS Hydraulics RVA0.M18

The RVA valve combines in one compact cartridge the typical function of shock relief valve and anti-cavitation through the built-incheck valve. In the relief function when the pressure at the Inlet (1) reaches the valve setting, the valve starts to open to tank (2)and thanks to the effect of the deflector integrated into the poppet it provides a limited pressure rise. The cartridge offers excellentresponse to load changes in hydraulic circuits requiring low internal leakage as well as limited hysteresis. Innovative design oninternal dampening part guarantees great stability. In the free reverse flow function a light bias spring allows for ease of flowpassage from side to nose (2 to 1) by lowering the internal seat.
