A high pressure, screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve
for three-way circuits requiring remote pilot actuation.
When in neutral, the HPD42-S50 allows flow from 3 to 2 bidirectionally while flow is blocked at 4.
On remote pilot signal at 1, the valve's spool shifts to allow flow between 3 and 4 while blocking at 2.
The spring chamber is vented to the tank through port 5.The vented spring chamber allows the valve to
be fully pressurized at 1, 2, 3, and 4 without affecting required pilot pressure at 5. Pressure at port 5
will increase the required pilot pressure at a 1:1 ratio.
