Ball valves were introduced in the 1950s. The industrial ball valve is a kind of industrial valves. With the rapid development of science and technology, the continuous improvement of production technology and product structure has rapidly developed into a major valve category in just 40 years.
Trunnion mounted ball valve body material: WCB, WC6, WC9, CF8, CF8M, CF3, CF3M, etc. The trunnion mounted American standard ball valve usually uses rubber, nylon and Teflon as the seat seal material, so its use temperature is affected by the valve seat.
Trunnion ball valve dimensions are following,include ANSI casting steel trunnion mounted ball valve,DIN casting steel trunnion mounted ball valve,ANSI forged steel trunnion mounted ball valve.
The use of trunnion mounted ball valves is very extensive and is widely known in many industrial processes. Then we should also know trunnion type ball valve maintenance so that we can work more smoothly in future operations.
The trunnion mounted ball valve is a high-performance ball valve suitable for various corrosive and non-corrosive media in ball valves. The trunnion mounted ball valve has low torque, stable sealing performance and long service life.
When to use a trunnion mounted ball valve ? Trunnion mounted ball valves are suit for following working conditions.
Trunnion ball valve weight are following,include ANSI casting steel trunnion mounted ball valve,DIN casting steel trunnion mounted ball valve,ANSI forged steel trunnion type ball valve.
Under normal circumstances, industrial valves are not tested for strength during use, but the valve body and bonnet or corrosion-damped valve body and bonnet should be tested for strength after repair. Trunnion mounted ball valve strength and tightness tests shall be performed prior to valve installation.
Ball valve is mainly used in connecting or blocking line medium, especially in the pleading agile open closed parts, such as emergency relief. Because the ball valve has a brief layout, less parts, light weight, good sealing performance advantages.
The ball valve is one of many fluid control valves. The opening and closing member is a circular spherical body with a hole, and the ball is rotated back and forth around the axis of the rod by 0-90° to achieve the purpose of opening or closing the flow.
