BUTTERFLY VALVE STRUCTURE

We are a valve manufacturer, API 6D Check Valve is one of our products, let me share with you the structure of Butterfly Valves

　　It is mainly composed of valve body, valve stem, butterfly plate and sealing ring. The valve body is cylindrical, with a short axial length and a built-in butterfly plate.

　　Features

　　1. Butterfly valve has the characteristics of simple structure, small size, light weight, low material consumption, small installation size, rapid switching, 90° reciprocating rotation, small driving torque, etc. It is used to cut off, connect, and adjust the medium in the pipeline. Offers good fluid control properties and shut-off sealing.

　　2. Butterfly valve can transport mud, with the least amount of liquid accumulated at the pipe mouth. 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 been quenched and tempered, and has good comprehensive mechanical properties, corrosion resistance and scratch resistance. When the butterfly valve is opened and closed, the valve stem only rotates and does not move up and down, the packing of the valve stem is not easy to be damaged, and the sealing is reliable. It is fixed with the cone pin of the butterfly plate, and the overhanging end is designed to prevent the valve stem from breaking out when the connection between the valve stem and the butterfly plate is accidentally broken.

　　5. The connection methods include flange connection, wafer connection, butt welding connection and lug wafer connection.

　　The drive forms include manual, worm gear drive, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation.

　　We have many other products, such as Flange End Globe Valve, welcome to our website!
