SPC5.S10 VALVE SERIES
Hybrid SAE10 Cartridge - 350 bar
Direct acting check valve
Pilot piston to open
DESCRIPTION
Normally closed, single pilot check valve. Cartridge is closed until sufficient pressure is applied on port 2 to reach the bias spring
setting, lift the poppet and allow free flow to 3. The valve is normally closed from 3 to 2. When sufficent pressure is applied on port
1, the pilot piston lifts the poppet from its seat and allows flow from 3 to 2. Very limited leakage in the check condition.
