FR08-20F

REGULATOR, PRESSURE COMPENSATED

Overview

Description

FR08-20F 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.
  • Compact, industry-common cavity.
