SVCV12-20 Valve

SYMBOL:SVCV12-20 Valve symbol

A solenoid-operated, 2-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 SVCV12-20 blocks flow from 2 to 1 and from 1 to 2.
When energized, the cartridge's poppet lifts to open the 2 to 1 flow path, while continuing to block flow from 1 to 2.
The SVCV12-20 is designed to fit into the VC12-3 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. At flows greater than 56.8 lpm (15 gpm) pressure drop will be lower if the optional port 2 is connected to port 1.

• 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.
• Cost effective cavity.
