Application
A cartridge valve designed as a three
position, four-way solenoid valve for
compact hydraulic integrated circuits.
Operation
When de-energized, the valve prevents
flow at all ports. When the upper
solenoid (S1) is energized, the valve
allows flow between the (2) and (1) ports
and the (3) and (4) ports. When the lower
solenoid (S2) is energized, the valve
allows flow between the (4) and (1) ports
and the (3) and (2) ports.
Operation of Manual Override Option: To
override, pull the knurled knob to
activate the coil “S1” function, or push
the knurled knob to activate the coil “S2”
function. Release the knurled knob to
return the center position.
Features
• High flow capacity with reduced space
• Continuous-duty solenoid.
•
Hardened precision spool and sleeve
for long life.
• Efficient wet-armature construction.
•
Cartridges are voltage
interchangeable.
•
Optional coil voltages and
terminations.
• Industry common cavity.
• Compact size.
