FD50-45

FLOW DIVIDER/COMBINER VALVE

Overview

Description

The FD50-45 is a screw-in cartridge, spool type flow divider/combiner valve. It provides pressure compensated proportional division of inlet flow or combining of two return flows regardless of system operating pressure conditions. The valve provides synchronizing flow in dividing and combining modes. The valve is intended for use in mineral based or synthetic hydraulic fluids with lubricating properties

Features

  • Hardened parts for long life.
  • Quiet, modulated response.
  • Wide operating flow range.
  • Synchronizing in dividing and combining modes.
  • Floating cage — high installation torque.
  • Industry-common cavity.
