PCV10 Check, Pilot-to-Open (PCV10)
An in-line-housed, pilot-operated, hydraulic check valve for use in blocking or load-holding circuits.
Product Operation
The PCV10 allows flow from B to A, while normally blocking flow from A to B.
Flow will be allowed from A to B when pressure is applied at X.
The check valve has a 4:1 pilot ratio, meaning that at least one-fourth of the load
pressure held at A is required at X to open the valve.
The check is spring-biased at 2 bar (30 psi) to assure holding in static or no-load
conditions. A sealed pilot piston option with check spring bias of 6.9 bar (100 psi)
is available.
Product Features
• Hardened seat for long life and low leakage.
• Optional sealed pilot piston.• Optional spring ranges.
• Check section is serviceable as a cartridge.
