DIRECTIONAL VALVES

PD10-S62 Piloted Directional Valve

DESCRIPTION

A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic cartridge valve.

OPERATION

In the neutral position, the PD10-S62 allows ﬂ ow between ports ➁ and ➂ and be-

tween ports

➃ and ➄ bidirectionally. When the remote pilot signal at ➀ exceeds the

force of the bias spring, the spool shifts to block ﬂ ow at all ports.

The spring chamber is vented to the tank through port

➅. The vented spring chamber

allows the valve to be fully pressurized at ports

➀, ➁, ➂, ➃ and ➄ without affecting

required pilot pressure. Pressure at

➅ will affect required pilot pressure.

FEATURES

• Hardened spool and cage for long life.

• Optional sealed spool between ports

➀ and ➁.

RATINGS

Maximum Operating Pressure: 250 bar (3625 psi) with standard Buna N seals.

Maximum Total Input Flow: 53 lpm (14 gpm) in any combination of ﬂ ows between

ports

➁ and ➂, and ports ➃ and ➄ (e.g., 2 &12 gpm, 7 & 7 gpm, or 10 & 4 gpm).
