NORMALLY CLOSED ELECTRO PROPORTIONAL VALVE CARTRIDGE

Overview

Description

PV08-23X is a solenoid operated, spool type, normally closed proportional flow control valve intended for use in combination with fixed area orifice as a pilot to control displacement of larger spools.

Operation

With inlet at port 1, the valve provides flow from port 2 proportional to the current applied.

Features

  • Excellent linearity and hysteresis characteristics.
  • Hardened spool and cage for long life.
  • Optional coil voltages and terminations.
  • Efficient wet-armature construction.
