Cast Steel Trunnion Ball Valve

The cast steel trunnion ball valve opening and closing member is driven by the valve stem and rotates around the axis of the valve stem. It is mainly used to cut off or turn on the medium in the pipeline, and can also be used for fluid regulation and control. The hard seal V-shaped ball valve has a strong shear between the V-shaped ball core and the metal valve seat of the hardfacing alloy. Shear force, especially suitable for media containing fibers, tiny solid particles. Cast steel ball valves are generally divided into handle cast steel ball valves, pneumatic cast steel ball valves, electric cast steel ball valves, cast iron ball valves, stainless steel ball valves, all copper ball valves.
