HDCV16 Valve

HDCV16 Valve symbol


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

The HDCV16 allows flow from V ports to C ports, while normally blocking flow in the
opposite direction. Flow will be allowed from C to V when pressure is applied to the
opposite side V port.
The valve has a 2:3:1 pilot ratio, so at least 43% of the load pressure held at either
C port is required at the opposite V port to open the flow passage.

• High pressure operation.
• Check section serviceable as a cartridge.
• Hardened seat for long life and low leakage.
• Optional sealed piston.
• Optional spring ranges.
• Low pressure drop.
• All HyPerformance™ products are tested to NFPA specification T2.6.1
   and are tested at a verification level of 90% and an assurance of 99%.
