HPCV16 Valve

SYMBOL:
HPCV16 Valve symbol

DESCRIPTION
An in-line housed, pilot-operated, hydraulic check valve for use in high pressure blocking or
load-holding circuits.

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 pressure 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.

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%.
