HPC10-J49 Valve

SYMBOL:HPC10-J49 Valve symbol
DESCRIPTION
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.

OPERATION
In the unpiloted state, the HPC10-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 and 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 17 bar (250 psi).

FEATURES
• Bi-directional flow.
• Balanced poppet.
• Low internal leakage.
• 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%.
