SP12-20

PROPORTIONAL SOLENOID VALVE 2 PORT, NORMALLY CLOSED

Overview

Description

A solenoid-operated, 2-way, normally closed,poppet-type, proportional, screw-in hydraulic cartridge valve, designed for low leakage blocking and load-holding applications.

Operation

When de-energized, the sp12-20xx acts as a check valve, allowing flow from 1 to 2,while blocking flow from 2 to 1. When energized, the poppet lifts to open the 2 to 1 flow path.

Features

  • Continuous-duty rated coil.
  • Efficient wet-armature construction.
  • Manual override option.
  • Optional waterproof E-Coils rated up to IP69K.
  • Industry common cavity.
  • Metering option.
