FD52-45

FLOW DIVIDING / COMBINING VALVE

Overview

Description

The FD52-45 is a screw-in cartridge, spool type flow divider/combiner valve.

Operation

The cartridge valve 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.

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.
