Casting Top Entry Ball Valve Gear Wcb

We manufacture and export Top Entry Ball Valve Gear WCB in Wenzhou, Zhejiang, China. Top entry ball valve is assembled from the top of body. Stem and ball are fixed to remove the possibility of stem blowout. Graphite is chosen for packing seal and bonnet gasket is flexible graphite and metal. The seats are inserted from both ends and sealed with flexible graphite. Spring is mounted at the seat step to help close valve. When the pressure rises, media flow into the back of seat and force the seats against the ball to guarantee the tight closure.
