ADJUSTABLE PRESSURE COMPENSATED PRIORITY FLOW REGULATOR VALVE CARTRIDGE

Overview

Description

FR12-33X is a screw-in, an adjustable, pressure compensated, priority type with reverse flowcheck flow control valve

Operation

The regulated flow increases from closed to fully open with counter-clockwise adjustment rotation. The valve will maintain the set flow regardless of pressure variations on the regulated or bypass port

Features

  • Bypass port 2 may be fully pressurized.
  • Hardened steel parts for long life.
  • Quiet, modulated response.
  • Industry-common cavity.
