1.The butterfly valve has the characteristics of simple structure, small size, light weight, low material consumption, small installation size, fast switching, 90° reciprocating rotation, and small driving torque. It is used to cut off, connect, and adjust the medium in the pipeline, has good fluid control characteristics and closed sealing performance.
2.The streamlined design of the disc makes the fluid resistance loss small, which can be described as an energy-saving product.
3.The valve stem is a through-rod structure. it has good comprehensive mechanical properties, corrosion and scratch resistance. 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 outgoing end is designed to prevent the outgoing type, so as to prevent the valve rod from collapsing when the connection between the valve rod and the butterfly plate is accidentally broken.
4.Connection methods include flange, wafer, butt welding and lug.
5.The driving form includes manual, worm gear transmission, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation.
