PD16-S50 Valve

PD16-S50 Valve symbol

A screw-in, cartridge-style, pilot-operated, spool-type, high pressure hydraulic directional valve
for three-way circuits requiring remote pilot actuation.

In neutral (unpiloted), the HPD16-S50 allows flow from 3 to 2 bidirectionally while flow is blocked at 4.
On remote pilot signal at 1, the valve shifts to allow flow between 3 and 4 while blocking at 2.
The spring chamber is vented to the tank through port 5, which is, optionally, O-ring sealed from the
cartridge flow paths. The vented spring chamber allows the valve to be fully pressurized at ports 1, 2, 3
and 4 without affecting required pilot pressure. Pressure at 5 will affect required pilot pressure.

• Hardened spool and cage for long life.
• All HyPerformance products are tested to the rigorous standards of the NFPA specification T2.6.1
   and are tested at a verification level of 90% and an assurance of 99%.
