Forged Trunnion Ball Valve
Forged Trunnion Ball Valve Description
A Forged Trunnion Ball Valve is a type of valve that is primarily used in pipelines for cutting off, distributing, and changing the flow direction of the medium. The valve is designed with a V-shaped opening, which also makes it an excellent choice for flow regulation. The opening and closing member of the valve is a ball, which rotates around the axis of the stem by 90 degrees to open or close.
The Forged Trunnion Ball Valve is easy to operate and quick to open and close, from fully open to fully closed with a 90° rotation, making it easy to control from a distance. In addition, it is easy to maintain, because the structure is simple, and the seal ring is generally movable, disassembly and replacement are relatively convenient. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and high vacuum or high pressure.
