FR50-23

ADJUSTABLE PRESSURE COMPENSATED RESTRICTIVE TYPE FLOW REGULATOR

Overview

Description

A screw-in, adjustable, pressure compensated, restrictive type with reverse flow check flow regulator cartridge valve

Operation

The valve opening increases from fully closed to fully open with counterclockwise adjustment rotation. With inlet at port 1 the FR50-23X valve will maintain preset flow rate from port 2 regardless of pressure variations in the circuit. The valve is intended for use with mineral based or synthetic fluids with lubricating properties

Features

  • Hardened parts for long life.
  • Quiet, modulated response.
  • Industry-common cavity.
