OPERATION

Solenoid Valve, Spool Type, 3-Position, 4-Way, High Flow (15-Size). When de-energized, the SV15-34-03 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. This valve

is a direct replacement for EDH 12/4307 and uses a metric M33x2 cavity (NCS 12/4) for high ow capability. The

SV15-34-03 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 300,000 cycles. Port 1 may

be pressurized to 150 bar, but is not intended for use as inlet (Tank only).
