SVCV08-20 Valve

SYMBOL:SVCV08-20 Valve symbol

DESCRIPTION
A solenoid-operated, 2-way, normally closed, poppet-type, bi-directional blocking, pilot-operated, screw-in hydraulic cartridge valve with outlet flow check designed for low leakage in load-holding applications.

OPERATION
When de-energized, the SVCV08-20 blocks flow in both directions.
When energized the poppet opens to allow flow from 2 to 1, while continuing to block flow from 1 to 2.
The SVCV08-20 is designed to fit into the VC08-3 cavity with the normal inlet at cavity port 3 (valve port 2), the outlet at cavity port 1 (valve port 1), and cavity port 2 blocked. The pressure drop will be substantially higher if cavity port 2 is selected as an alternate outlet port.

Operation of Manual Override Option: To override, push button in, twist counterclockwise
180°, and release. In this position, the valve will remain open. To return to normal operation, push button in, twist clockwise 180°, and release. Override will be detented in this position.

FEATURES
• Continuous-duty rated coil.
• Hardened seat for long life and low leakage.
• Optional coil voltages and terminations.
• Cartridges are voltage interchangeable.
• Manual override option.
• Optional waterproof E-Coils rated up to IP69K.
• Industry common cavity – compact size.
