SVRV12-26F Spool, 2-Way, Normally Open,
DESCRIPTION
A solenoid-operated, two-way, spool-type, normally open, screw-in, hydraulic
pressure-relief valve.
OPERATION
When the coil is de-energized, the SVRV12-26F is open, allowing fl ow from ➀ to ➁.
When the coil is energized, fl ow from
➀ to ➁ is blocked. When the coil is energized
and the pressure at
➀ exceeds the relief setting, the valve will open to allow fl ow
from
➀ to ➁.
FEATURES
• Continuous-duty rated solenoid.
• Hardened spool and cage for long life.
• Effi cient wet-armature construction.
• Cartridges are voltage interchangeable.
• Optional waterproof E-Coils rated up to IP69K.
• Unitized, molded coil design.
• Industry common cavity.
