PD16-S50 Valve

SYMBOL:
PD16-S50 Valve symbol

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

OPERATION
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.

FEATURES
• Hardened spool and cage for long life.
• 50, 70, 100 and 150 psi bias springs available.

RATINGS
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;
