RVQ0.S10 VALVE SERIES
SAE10 Cartridge - 420 bar
Pilot Operated - Spool Type
DESCRIPTION
A screw-in, cartridge style, pilot operated (2-stage), spool type, normally closed, hydraulic relief 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
(spool type) that throttles oil flow to tank (2). The cartridge offers smooth transition in response to load changes in demanding
hydraulic circuits. Fast, smooth response and limited hysteresis.
