SV12-25

SOLENOID VALVE SPOOL, 2 PORT, NORMALLY OPEN

Overview

Description

A solenoid-operated, 2 port, normally open, direct-acting, spool-type, screw in hydraulic cartridge valve, designed to function as a bidirectional blocking valve.

Operation

When de-energized, the SV12-25 allows flow in both directions. When energized, the valves spool shifts to block flow in both directions.

Features

  • Continuous-duty rated coil.
  • Hardened seat for long life and low leakage.
  • Optional coil voltages and terminations.
  • Efficient wet-armature construction.
  • Cartridges are voltage interchangeable.
  • Unitized, molded coil design.
  • Manual override option.
  • Optional waterproof E-Coils rated up to IP69K.
  • Cost-effective cavity.
