SV12-34

SOLENOID VALVE SPOOL, 3 PORT, 2 POSITION

Overview

Description

A solenoid operated, two position, three way, direct acting spool valve. When de-energized, the SV12-34X allows flow from port 2 to port 1, while blocking flow at port 3. When energized, the spool shifts to open from port 3 to port 2 while blocking port 1. While port 1 may be fully pressurized, it is not intended to be used as an inlet

Features

  • Manual override options.
  • Continuous-duty rated coil.
  • Hardened precision spool and cage for long life.
  • Optional coil voltages and terminations.
  • All ports may be fully pressurized.
  • Heavy-duty waterproof E‑Coils rated up to IP69K.
