SV10-21 Poppet, 2-Way, Normally Open
DESCRIPTION
A solenoid-operated, 2-way, piloted, poppet-type, normally open, screw-in, hydraulic
cartridge valve designed for low leakage in load-holding applications.
OPERATION
When de-energized, the SV10-21 allows fl ow from ➁ to ➀. Flow from ➀ to ➁ is
severely restricted in this mode. If the
➀ to ➁ path is required, see model SV10-23,
page 1.053.1.
When energized, the valve’s poppet closes on its seat, blocking fl ow in the
➁ to ➀
direction. In this mode the cartridge will allow
➀ to ➁ fl ow 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.
• Industry common cavity.
• Manual override option.
• Optional waterproof E-Coils rated up to IP69K.
