A solenoid-operated, two-way, pilot-operated, poppet-type, normally closed, screw-in hydraulic cartridge valve with outlet flow check, designed for low leakage in load holding applications.
When de-energized, the SVCV08-20 blocks flow from ➁ to ➀ and from ➀ to ➁When energized, the cartridge’s poppet lifts to open the ➁ to ➀ flow path, while continuing to block flow from ➀ to ➁The SVCV08-20 is designed to fi t into the VC08-3 cavity with the normal inlet at cav-
ity port 3 (valve port ➁), the outlet at cavity port ➀ (valve port ➀), and cavity port ➁ blocked. The pressure drop will be substantially higher if cavity port ➁ is selected as an alternate outlet port.
Operation of Manual Override Option: To override, push button in, twist counter-
clockwise 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.
