SP12-21

SOLENOID PROPORTIONAL VALVE POPPET, 2 PORT, NORMALLY OPEN

Overview

Description

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

Operation

When energized, the SP12-21 acts as a check valve, allowing flow from port 1 to port 2, while blocking flow from port 2 to port 1. When de-energized, the poppet lifts to open the port 2 to port 1 flow path.

Features

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