By manually turning the handwheel, the thread between the handwheel and valve stem allows the valve stem to move up or down, which in turn raises or lowers the valve plate connected to the valve stem. This achieves the function of opening and closing the valve.
1.Low fluid resistance.
2.Opening and closing requires less effort.
3.The medium flow direction is not restricted, there is no disturbance to the flow and no pressure drop.
4.The design is simple, the structural length is short, quailty manufacturing process, wide range of applications.
