SVCV12-20 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 SVCV12-20 blocks fl ow from 2 to 1 and from 1 to 2.
When energized, the cartridge’s poppet lifts to open the 2 to 1 fl ow path, while
continuing to block fl ow from 1 to 2.
The SVCV12-20 is designed to fi t 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 fl ows greater than 56.8 lpm (15 gpm) pressure drop will be
lower if the optional port 2 is connected to port 1.
FEATURES
• Continuous-duty rated coil.
• Hardened seat for long life and low leakage.
• Optional coil voltages and terminations.
• Cartridges are voltage interchangeable.
• Optional waterproof E-Coils rated up to IP69K.
• Cost effective cavity.
