Fully Welded Ball Valve

FUWEI valve has very professional experience in manufacturing and supplying of Fully Welded Ball Valve well use in different industries.

The Fully Welded Ball Valve manufactured by FUWEI valve use Ct20(20#) carbon steel pipes to welded or use forging to welded that the body will be fully welded as one piece integral body.   Due to the ball valve is fully welded structure, it reduces the risk of leakage. Integral body will ensure the tightness of body. The support plate structure also increases performance stability. Fully welded ball valves are used mainly in gas transmission,water heating and distribution pipeline, typical for underground and buried installation. Stem height can be adjusted according to pipe construction & design requirements.
