SVRV10-26 Valve
U.S. Patent 7,137,406

SYMBOL:
SVRV10-26 Valve symbol
DESCRIPTION
A solenoid-operated, 2-way, normally open, spool-type, screw-in hydraulic cartridge
valve with pressure relief.

OPERATION
When the coil is activated, the pilot closes the drain flow and the spool closes port 2.
In this position, the valve 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.


FEATURES
• Various pressure ranges.
• Continuous-duty rated coil.
• Hardened spool and cage for long life.
• Optional coil voltages and terminations.
• Cartridges are voltage interchangeable.
• Efficient wet-armature construction.
• Optional waterproof E‑Coils rated up to IP69K.
• Industry common cavity.
