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
