Swing-type check valves are widely used in pipeline transportation such as petrochemical, pharmaceutical, and electric power. In these systems it is often necessary to transport some oil, steam, nitric acid, and highly oxidizing media.

The swing check valve function is to prevent the medium in the pipeline from flowing backward. The valve of the opening and closing part is opened or closed by the flow of the medium and the force to prevent the back flow of the medium from being called a check valve.

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.

There are installation instruction for kinds of check valve,include swing check valve,lift check valve etc.
