HIGH PRESSURE PILOT OPERATED CHECK VALVE
Overview
Symbol
Description
The HDCV is a double pilot operated, hydraulic check valve for use in
blocking or load holding circuits
Operation
The valve 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 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

seal code U
