HPCV16 HyPerformance (HPCV16)
An in-line-housed, pilot-operated, hydraulic check valve for use in high pressure blocking or load-holding circuits.
Product Operation
The HPCV16 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 2.3:1 pilot ratio, meaning that at least 44 percent of the load pres-sure held at A is required at X to open the valve.
The check is spring-biased at 1.7 bar (25 psi) or 4.1 bar (60 psi) to assure holding in static or no-load conditions. A sealed pilot piston option 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.• All HyPerformance products are tested to the rigorous standards of the NFPA specification T2.6.1.• All HyPerformance valves are tested at a verification level of 90% and an assurance of 99%.
