A high pressure, two-way, bi-directional, pilot-to-open, balanced poppet-type, screw-in,
cartridge-style, hydraulic directional element designed to function as a load-holding or
blocking valve in applications requiring low internal leakage.
In the unpiloted state, the HPC42-J49 allows flow from 1 to 2 bi-directionally. On remote
pilot signal at port 4, the valve shifts to block flow from ports 1 to 2 bi-directionally. The
spring chamber is vented to port 3. Pressure at port 3 will directly affect the pilot pressure
required to shift the valve must be added. The hydraulically balanced poppet will allow
ports 1 and 2 to be fully pressurized without affecting required pilot pressure to actuate the
valve. With port 3 vented, the valve will fully shift with a minimum pilot pressure of 14 bar (200 psi).
• Bi-directional flow.
• Balanced poppet.
