A screw-in, cartridge-style, pilot-operated, hydraulic check valve for use in blocking or load-holding circuits.
The PC10-32 allows flow passage from ➁ to ➂, while normally blocking flow from ➂ to ➁. Flow will be allowed from ➂ to ➁ when pressure is applied at ➀The cartridge has a 2:1 pilot ratio, meaning that at least one-half of the load pressure
held at ➂ is required at ➀ to open the valve.The check is spring-biased 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 piston.
• Industry common cavity.
Operating Pressure: 240 bar (3500 psi)
Flow: See Performance Chart
Internal Leakage: ➂ to ➁: 0.25 cc/minute (5 drops/minute) max. at 240 bar (3500 psi) ➁ to ➀ (without sealed piston): 115 cc/minute (7 cu. in./minute) max. at 240 bar (3500 psi)
Pilot Ratio: 2:1
Check Bias Spring: 2.07 bar (30 psi); With sealed piston option: 6.9 bar (100 psi) minimum
