PD10-45 Valve

PD10-45 Valve circuitsymbol

A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve
for two-way circuits requiring remote pilot actuation and vented spring chamber.

In neutral (unpiloted), the PD10-45 allows flow between 3 and 2. The spring chamber
is directed to port 4. On remote pilot signal at 1, the valve shifts to allow flow between 3 and 2.
Since port 4 is common to the spring chamber, pressure on 4 will directly (1:1) affect the pilot
pressure required, and must always be added to the bias spring value.

• Hardened spool and cage for long life.
• Industry-common cavity.

Operating Pressure: 240 bar (3500 psi)
Flow: up to 45 lpm (12 gpm)
