A solenoid-operated, 2-way, normally open, poppet-type, screw-in hydraulic cartridge
valve designed for low leakage in load-holding or blocking applications.
When de-energized, the SV12-23 allows flow from 2 to 1 and from 1 to 2. With the sensor
option, the neutral sensor will signal OFF or LOW and ON or HIGH. When energized, the
valve closes, blocking flow from 2 to 1. In this mode, flow from 1 to 2 will be allowed after
overcoming the solenoid force. This requires 3.4 to 10.3 bar (50 to 150 psi). With the sensor
option, the neutral sensor will signal ON or HIGH, LOW or OFF, or BOTH for Dual redundancy.
Operation of Manual Override Option: To override, push and hold override button.
• Continuous-duty rated coil.
• Hardened seat for long life and low leakage.
• Optional coil voltages and terminations.
• Efficient wet-armature construction.
• Cartridges are voltage interchangeable.
• Unitized, molded coil design.
• Manual override option.
• Optional waterproof E-Coils rated up to IP69K.
• Cost-effective cavity.
