PRIORITY FLOW REGULATOR WITH BUILT-IN RELIEF VALVE U.S. PATENT No. 7,063,100

Overview

Description

Frrv12-41f/x is a screw-in, cartridge type, combination valve. It includes a pressure compensated, non adjustable priority type flow regulator and a pressure relief valve

Operation

With inlet at port 1, it maintains a constant flow rate from port 3 regardless of load pressure changes at priority port 3 or bypass port 2. When the load in priority line exceeds preset value, the valve relieves pressure to port 4

Features

  • Two valve functions in one, industry-common cavity.
  • Adjustments cannot be backed out of the valve.
  • Relief valve adjustments prohibit relief valve spring from going solid.
  • Quiet, modulated response.
  • Hardened parts for long life.
