SPC4.M18 VALVE SERIES

METRIC Cartridge - 350 bar

Direct acting check valve

Pilot piston to open

DESCRIPTION

Cartridge style, 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.

The performance chart illustrates flow handling

capacity for significant spring options.

p/Q curves are recorded at TOil = 40°C and 46

cSt.
