4-Way, 2-Position Spool
SV08-24-08
OPERATION
Solenoid Valve, Spool Type, 2-Position, 4-Way, 08-size. When de-energized,
the SV08-24-08 allows ow from ports 2 and 4 to port 1, while port 3 is
blocked. When energized, the spool shifts to allow ow from port 3 to 4,
and from 2 to 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 connecting both sides of a motor (free-wheeling) or
cylinder to tank when not energized. Then, when energized, the valve
provides unidirectional ow to the motor or cylinder. 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).
