1. The butterfly valve has the features of simple structure, small size, light weight, low material consumption, small installation size, rapid switching, 90 degree reciprocating rotation, and small driving torque. it is used to cut off, connect, and adjust the medium in the pipeline. Has good fluid control features and shut-off sealing torque.

2. The butterfly valve can transport mud, and the liquid cumuled at the mouth of the pipe is the least. At low pressure, a good seal can be achieved. Good adjustment performance.

3. The streamlined design of the butterfly plate makes the loss of fluid resistance small, which can be described as an energy-saving product.

4. The valve stem is a through-rod structure, which has good comprehensive mechanical properties, corrosion resistance and scratch resistance after quenching and tempering treatment. when the butterfly valve is opened and closed, the valve stem only rotate and does not move up and down. The packing of the valve stem is not easy to damage and the seal is reliable . It is fixed with the taper pin of the butterfly plate, and the provelding end is designed to prevent the valve stem from collapseding when the joint between the valve stem and the butterfly plate breaks accidentally.

5. The connection methods include flange connection, clamp connection, butt welding connection and lug clamp connection.The driving forms include manual, worm gear transmission, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation.
