SVRV12-26F Valve
U.S. Patent 7,137,406

SVRV12-26F Valve symbol
A solenoid-operated, 2-way, normally open, spool-type, screw-in hydraulic cartridge valve with pressure relief.

When the coil is activated, the pilot closes the drain flow and the spool closes port 2. In this position, the SVRV12-26F works as a relief valve, relieving flow from port 1 to 2. The pilot opens when the pressure at port 1 exceeds the set pressure. Pilot flow is discharged to port 2.

• 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.
