Casted Trunnion Ball Valve

Overview

Casted Trunnion Ball Valve is a valve whose opening and closing parts are driven by the valve stem and rotate around the axis of the ball valve. It can be used for fluid adjustment and control, and it is also particularly suitable for media containing fibers, small solid particles, etc. Casted Trunnion Ball Valve has a wide range of applications, from simple water pipelines to highly corrosive chemicals to nuclear power plants.

Casted Trunnion Ball Valve has low fluid resistance, and its resistance coefficient is equal to that of pipe sections of the same length. In addition, its structure is relatively simple, small in size and light in weight. In addition, it is tight and reliable, and the sealing surface material of the ball valve is widely used in plastics and has good sealing performance. It has also been widely used in vacuum systems.
