Free-valve's butt welding butterfly valves are suitable for high temperature , high pressure , corrosion etc. Its are quarter-turn valves which are used for isolating or regulating flow .They are favoured for being lighter in weight, requiring less support and are suitable for water and gas, which makes them useful across industrial, mining and power applications.
Features:
1. Reliable sealing, convenient operation, opening and closing fast.
2. This kind of valve with no flange, which makes pipe elegantly and binding up conveniently.
3. It adopt triple offset elasticity or multiple layers hard sealing configuration, the hermetical capability can reach to reliable sealing performance.
