SV10-21 Poppet, 2-Way, Normally Open (SV10-21)
A solenoid-operated, 2-way, piloted, poppet-type, normally open, screw-in, hydraulic cartridge valve designed for low leakage in load-holding applications.
Product Operation
When de-energized, the SV10-21 allows flow from 2 to 1. Flow from 1 to 2 isseverely restricted in this mode. If the 1 to 2 path is required, see model SV10-23, page 1.053.1.
When energized, the valve’s poppet closes on its seat, blocking flow in the 2 to 1 direction. In this mode the cartridge will allow 1 to 2 flow 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.
Product Features
