Check Valves Series SPR (Parker), C4V (Denison)

Catalogue HY11-3500/UK

Characteristics Direct operated check valves are available with both Parker (series SPR) and Denison (series C4V) ordering codes. Check valves allow free flow from A to B. The counter direction is blocked. The SPR/C4V series are equipped with a leak-free seat type cartridge. Function The pressure arising in port A lifts the poppet from the valve seat and releases the flow to B. In the counter direction, the spring and the pressure on top of the cartridge hold the poppet onto the seat and block the flow.
