An in-line housed, pilot-operated, hydraulic check valve for use in
blocking or load-holding circuits.
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.
This 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.
• Hardened seat for long life and low leakage.
• Optional sealed pilot piston.
• Optional spring ranges.
• Check section is serviceable as a cartridge.
Operating Pressure: 240 bar (3500 psi)
Flow: up to 60 lpm (16 gpm)
Maximum Internal Leakage at 240 bar (3500 psi):
A to B: 0.25 cc/minute (5 drops/minute)
B to X without sealed piston: 245 cc/minute (15 cu. in./minute)
Pilot Ratio: 4:1
Check Spring Bias: 2.07 bar (30 psi); with sealed piston option: 6.9 bar (100 psi)
