FR08-30F

FLOW REGULATOR PRESSURE COMPENSATED

Overview

Description

The FR08-30F is a screw-in, cartridge style, pressure compensated, non-adjustable hydraulic flow regulator valve. It CAN be used as a priority type flow regulator, delivering the pump flow to priority port 3 first, then bypassing excess to port 2; or a restrictive type, 2-way flow regulator when the bypass port 2 is blocked

Operation

The valve maintains a constant flow rate from port 3 regardless of pressure variations in the system downstream of priority port 3 or in bypass leg at port 2. All ports may be fully pressurized

Features

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