API Butterfly Valve

Type：API Butterfly Valve

Features:

Size: 2”-48”

Pressure: Class 150~600

Material: Cast, ASTM, Stainless Steel, Cast Steel, Alloy steel,

Design: API 6D

Structure: tri-eccentric

Ends: ANSI B16.5.

Predominance:

The API series of butterfly valves has several connection types such as clamp,flange,welding,protruding ear type(socket around body).and uses 3-dimension eccentric structure.with almost no attrition between seat and disc.with Function of sealing tighter and tighter and no matter under condition of sub zero or high tem-Perature of high pressure all have fine sealing performance.lt is is widely utilzed in foodstuff,pharmacy,petroleum,chemical industry,light industry,textile,metallurgy,mine,energy etc,as well as construction,environmental protection,water supply and drainage piping for opening and dosing or as just capacity of medium.
