SV12-23 Poppet, 2-Way, Normally Open
DESCRIPTION
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.
OPERATION
When de-energized, the SV12-23 allows bidirectional fl ow from ➁ to ➀.
When energized, the valve’s poppet closes to block fl ow from
➁ to ➀. In this mode,
the cartridge allows free reverse fl ow from
➀ to ➁ after overcoming the solenoid force
(requires 3.4 to 10.3 bar / 50 to 150 psi).
Operation of Manual Override Option: To override, push and hold override button.
FEATURES
• Continuous-duty rated solenoid.
• Hardened seat for long life and low leakage.
• Optional coil voltages and terminations.
• Effi cient 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.
