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