RVC0.S08 VALVE SERIES

SAE08 Cartridge - 350 bar

Direct acting - Poppet type

DESCRIPTION

A screw-in, cartridge style, direct acting, poppet type, normally closed hydraulic relief valve. It’s typically used to protect hydraulic

components from pressure transients. When the pressure at the Inlet (1) reaches the valve setting, the valve starts to open to tank

(2) throttling flow to minimize the pressure rise. The innovative geometry of the deflector provides in fact a very low rise rate, and

the poppet design guarantees great stability. The cartridge offers quick response to load changes in hydraulic circuits requiring low

internal leakage as well as limited hysteresis. NOTE: the RVC0 in the standard configuration can be used in crossover relief

applications.
