OPERATION
Solenoid Valve, Spool Type, 3-Position, 4-Way, High Flow (15-Size). When de-energized, the SV15-34-04 allows ow
from port 3 to port 1, while ports 2 and 4 are blocked. 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 port 1. Follow the “Operating Envelope” limits to ensure shifting of the valve during operation.
This valve is a direct replacement for EDH 12/4308. The SV15-34-04 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.
APPLICATIONS
These valves are primarily used in mobile and industrial
applications for controlling the direction of the ow in a circuit.
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 is not intended for use as inlet
(Tank only).
