Butterfly valves have been around for a long time, and are used for a variety of applications. They made their first appearance during the 1930s, and have been utilized by several industries ever since. Often made out of cast iron, butterfly valve's name is based from the functionality of its disc.
The wafer butterfly valve is one of the most common types of valves in industrial pipelines. The structure of wafer butterfly valve itself is relatively small. It is only necessary to put the butterfly valve in the middle of the flange at both ends of the pipe, and use the stud bolt to pass through the pipe flange and the pair.
The manual valve is a valve operated by the handle and the hand wheel, and is a commonly used valve on the equipment pipeline.
Valves are the most common equipment in chemical companies. It seems easy to install valves, but if they are not implemented in accordance with the re...

MINOTAUR series replaceable seat high performance butterfly valve
Product Features of Flange Type Soft Seal Butterfly Valve:
1. Compact and lightweight, easy to disassemble and maintain, and can be installed in any position.
2.Simple and compact structure, small operating torque, 90 ° rotation to open quickly, convenient operation, labor-saving and dexterous.
3. The flow characteristics are straight, and the adjustment performance is good.
4. The connection between the butterfly plate and the valve stem adopts a pinless structure, which overcomes the possible internal leakage points.
5. The outer circle of the butterfly plate adopts a spherical shape, which improves the sealing performance and prolongs the service life of the valve. It still maintains zero leakage when it is opened and closed under pressure for more than 50,000 times.
6. The sealing material is resistant to aging and corrosion, the seals are replaceable, and the seal is reliable to achieve a two-way seal.
7. The butterfly board can be spray coated according to user requirements, such as nylon or PTFE.
8. The valve can be designed into flange connection and wafer connection.
