ANSI Trunnion Type Spherical Valve

ANSI Trunnion type Spherical Valve  

 is mainly used to cut off or control the pipeline and medium.The fixed ball valve is a kind of common valve applied in the condition with high pressure and large diameter for the medium like water,steam, oil and other kind of corrosive medium.

Benefits

1.Produced with full bore and necking design, the fixed type ball valve is offered int one-piece,two-piece,and three-piece design.
2.Designed in fixed structure,the double-side sealing can be realized.
3.The simple structure makes the larger diameter available.
4.Since the valve seat is manufactured with fireproof structure,in case of fire,the flange connection fixed is safe and reliable due to outstanding sealing performance.
5.Offered with spring-plunger type static extraction there is a static access formed between the ball and stem and valve body and stem to avoid the accumulation of the static.
