SOLENOID VALVE BI-DIRECTIONAL, NORMALLY CLOSED

Overview

Description

A solenoid-operated, 2 way, normally closed, bi-directional, screw-in hydraulic cartridge valve, designed to function as a load holding or blocking valve in applications requiring low internal leakage bi-directionally

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.
