An in-line housed, pilot-operated, hydraulic check valve for use
in blocking or load-holding circuits.
The PCV16 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 3.8:1 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 1.7 bar (25 psi) to assure holding in static or no-load conditions.
A sealed pilot piston option 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 151 lpm (40 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: 3.8:1
Check Spring Bias: 1.7 bar (25 psi)
