Pressure Seal Globe Valve

Description

Overview

Pressure Seal Globe Valves have high Cv factors to minimize pressure drop across the system, lowering operating costs.

  • Uncomplicated design has segment retaining ring and mild steel silver plated (or graphite) gasket to aid disassembly and provide maximum bonnet seal
  • Uniquely designed line contact between disc and seat results in lower seating torque, permitting faster set up
  • The guided disc option facilitates seating and prevents vibration during high velocities and pressure drops
  • heavy duty disc available in plug, ball or V-port design
  • heavy duty, full ported ring threaded into body for easy maintenance
  • choice of plug or ball disc
  • OS&Y construction
  • Flanged or butt weld ends
  • full port design
  • renewable seat rings-also available seal welded
  • horizontal service
  • male and female bonnet joint
