Manufacturers of Floating Ball Valve

We offers 1/2/3 piece Design ball valve in Full / Reduce Port design with Flanged end connections, ball valves has split body design which meets all the requirements of ASME B16.34 for Class 150 / 300 / 600 ball valves. The Blow-Out Proof Stem floating Ball Design precision engineered valves have machined solid stainless steel ball and hollow ball with relief hole in the stem slot prevents build-up of cavity pressure while the valve is in the open position.

A floating ball valve is a valve with seat supported ball that is pushed by upstream pressure towards the downstream seat to ensure sealing. The DN of the floating ball valves range is limited by the capability of seat’s material to support the pressure, temperature and weight of the ball.
