FR50-20F

FLOW REGULATOR PRESSURE COMPENSATED

Overview

Description

The FR50-20F is a screw-in, cartridge style, fixed orifice, pressure compensated, hydraulic flow regulator valve (restrictive type)

Operation

The valve maintains a constant flow rate from port 1 to port 2 regardless of load pressure changes. Reverse flow returns through the control orifice and is non-compensated

Features

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