DESCRIPTION An in-line housed, pilot-operated, hydraulic check valve for use in blocking or load-holding circuits. 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. 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. FEATURES • Hardened seat for long life and low leakage. • Optional sealed pilot piston. • Optional spring ranges. • Check section is serviceable as a cartridge. RATINGS 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) Temperature: -40 to 100°C (-40 to 212°F) with Buna seals; -26 to 204°C (-15 to 400°F) with fluorocarbon seals. Filtration: See page 9.010.1 Fluids: Mineral-based or synthetics with lubricating properties at viscosities of 7.4 to 420 cSt (50 to 2000 sus); See Temperature and Oil Viscosity, page 9.060.1 Installation: No restrictions; See page 9.020.1 Seal Kit (for CV10-20): SK10-2x-T; See page 8.650.1 Piston Seal: See Dimension Drawing Pilot Piston Service Part Numbers: O-Ring (1): Buna 6001014; Fluorocarbon 6003014 Back-ups (2): Buna 6011014; Fluorocarbon 6011014 |
