Solenoid Valve, Spool Type, 3-Position, 4-Way, 08-size. When de-energized, the SV08-34-03
is open center, and opens ow between all four ports. When coil S1 is energized, the spool
shifts to allow ow from port 3 to port 4, and from port 2 to 1. When coil S2 is energized,
the spool shifts to allow ow from port 3 to port 2, and from port 4 to 1. Follow the
“Operating Envelope” limits to ensure shifting of the valve during operation. The SV08-
34-03 comes standard with a one-direction, push-pin manual override. When the manual
override is pushed, the spool shifts following the logic of energizing S2.

These spool-type valves are primarily used in mobile and industrial applications for
controlling the direction of the ow in a circuit. Solenoid spool-type valves are direct
acting and respond quickly to coil voltage input. Spool valves will have some leakage due
to spool clearance, so if your application requires no leakage at the working port(s), apply
a low leakage poppet valve(s), like PO check valve, counterbalance valve, etc., in addition
to this solenoid valve. This valve can operate with an inlet pressure of 315 bar on port 3 for
500,000 cycles. Port 1 may be pressurized to 210 bar, but is not intended for use as inlet
(Tank only).
