SVCV08-21 Poppet, 2-Way, Normally Open . . .
DESCRIPTION
A solenoid-operated, two-way, pilot-operated, poppet-type, normally open, screw-in
hydraulic cartridge valve with outlet fl ow check, designed for low leakage in load
holding applications.
OPERATION
When energized, the SVCV08-21 blocks fl ow from ➁ to ➀ and from ➀ to ➁.
When de-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 SVCV08-21 is designed to fi t into the VC08-3 cavity with the normal inlet at
cavity port 3 (valve port
➁), the outlet at cavity port ➀ (valve port ➀), and with cavity
port
➁ blocked.
Operation of Manual Override Option: To override, push and hold override button.
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.
