U.S. Patent 7,137,406
SYMBOL: |
DESCRIPTION
A solenoid-operated, 2-way, normally open, spool-type, screw-in
hydraulic cartridge valve with pressure relief.
OPERATION
When de-energized, the SVRV12-26F allows flow from 1 to 2. When the coil is energized, flow from 1 to 2 is blocked. When the coil is energized and the pressure at 1 exceeds the relief setting,
the valve will open to allow flow from 1 to 2.
FEATURES
• Continuous-duty rated coil.
• Hardened spool and cage for long life.
• Cartridges are voltage interchangeable.
• Efficient wet-armature construction.
• Optional waterproof E-Coils rated up to IP69K.
• Industry common cavity.
