The FEP Lined Flanged Bellows Sealing Single-Seat Globe Valve,Because seat and disk designs give flow characteristics with proportionate correlations between valve lift and flow rate, CNZPV globe valves are particularly efficient for throttling service. This ensures precise flow management and control. the globe valves equipped with a layer of fluoroplastic coating on both the valve body and valve inner parts surfaces that come into contact with the fluid. This effectively isolates the corrosive media from any metal contact, providing excellent protection against corrosion for all metal materials.The lined bellows sealing globe valves also equipped with lined bellows pipe,it provides a more stable sealing performance,suitable for more harsh working conditions and ensures zero leakage.
