A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve
for three-way circuits requiring remote pilot actuation.
In neutral (unpiloted), the PD16-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.
• 50, 70, 100 and 150 psi bias springs available.
Operating Pressure: 240 bar (3500 psi)
Flow: up to 170 lpm (45 gpm)
Maximum Internal Leakage at 207 bar (3000 psi): 245 ml/minute (15 cu. in./minute);
Zero leakage from port 1 to port 2 with sealed spool
Temperature: -40 to 100°C (-40 to 212°F) with Buna seals;
-26 to 204°C (-15 to 400°F) with fluorocarbon seals;
-54 to 107°C (-65 to 225°F) with polyurethane seals
Filtration: See page 9.010.1
Fluids: Mineral-based or synthetics with lubricating properties at viscosities of
7.4 to 420 cSt (50 to 2000 sus); See Temperature and Oil Viscosity, page 9.060.1
Installation: No restrictions; See page 9.020.1. A 6-way body can be used for this valve by
plugging body port 2 and using body ports 3, 4, 5 and 6 as ports 2, 3, 4 and 5 for the valve.
