4-Way, 2-Position Spool
SV08-24-04

OPERATION

Solenoid Valve, Spool Type, 2-Position, 4-Way, 08 size. When de-energized, the
SV08-24-04 allows ow from port 3 to port 1, while ports 2 and 4 are blocked.
When energized, the spool shifts to allow ow from port 3 to port 4, and from
port 2 to port 1. Follow the “Operating Envelope” limits to ensure shifting of the
valve during operation.

APPLICATIONS

These spool-type valves are primarily used in mobile and industrial applications
for controlling the direction of the ow in a circuit, like motors or cylinders. Can
be used in combination to duplicate a four-way, three-position valve, creating
an economical, compact function. 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 is
not intended for use as inlet (Tank only).
