Description
The Simplex patented 3 position/3-way,
“Suc-O-Matic” Valve draws hydraulic
oil out of any single-acting cylinder. In
the retract position, the valve generates
enough suction to fully retract any
single-acting load return cylinder
automatically.
■ Fully Retract load return cylinders.
■ Retracts spring return cylinders up
to 33% faster.
■ Full retraction regardless of weak
springs or mounting.
The Simplex patented Solenoid
Valve is available in a 3-way Suc-O-
Matic version for single-acting
cylinders and a 4-way version for
double-acting cylinders.
■ Suc-O-Matic valve capability.
■ Long life - Patented construction.
■ Largest porting (lowest back
pressure) available.
■ Optional coils: 12 VDC, 115 VAC,
230 VAC.
■ Includes manual override.
■ Direct bolt interchange with Simplex
manual valves.
■ Designed to handle surge flow
conditions.
■ Comes equipped with 6 meter cord
and pendant switch.
Both Simplex manual & solenoid
valves are available for remote or inline
application. Remote valves are perfect
for multiple operating systems, or
special fixturing and mounting applications.
They are available with tandem or
closed centers.
■ Available in manual or solenoid.
■ Includes mounting holes.
■ Available in closed center or tandem.
■ Ideal for independent control of two
or more cylinders.
*Remote versions do not include retract feature.
