PROPORTIONAL SOLENOID VAVLE 2 POSITION, 2 WAY, CLOSED SPOOL

Overview

Description

A solenoid-operated, 2 port, normally closed, direct acting spool type proportional, screw in hydraulic cartridge valve designed to operate as a bi-directional metering valve. When de-engergized, the sp08-24xx blocks flow in both directions. When the valve is partially energized (see performance curve) the valve begins to throttle flow. When fully energized, the spool opens to allow bi-directional flow

Features

  • Industry-common cavity.
  • Continuous-duty rated coils.
  • Efficient wet-armature construction.
  • Allow bi-directional flow when fully energized.
  • Optional waterproof E-Coils rated up to IP69K.
