SVCV08-20 Poppet, 2-Way, Normally Closed . . .

DESCRIPTION

A solenoid-operated, two-way, pilot-operated, poppet-type, normally closed, screw-in

hydraulic cartridge valve with outlet ﬂ ow check, designed for low leakage in load

holding applications.

OPERATION

When de-energized, the SVCV08-20 blocks ﬂ ow from ➁ to ➀ and from ➀ to ➁.

When energized, the cartridge’s poppet lifts to open the

➁ to ➀ ﬂ ow path, while

continuing to block ﬂ ow from

➀ to ➁.

The 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.

FEATURES

• Continuous-duty rated coil.

• Hardened seat for long life and low leakage.

• Optional coil voltages and terminations.

• Manual override option.

• Cartridges are voltage interchangeable.

• Optional waterproof E-Coils rated up to IP69K.

• Industry common cavity.

• Compact size.
