What is a wafer butterfly valve？
The wafer butterfly valve has simple structure, small size and light weight, it is only composed of a few parts. And just rotate 90 °to quickly open and close, the operation is simple, and the valve has good fluid control characteristics. When the butterfly valve is in a fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body. Therefore, the pressure generated by the valve is small, so it has better flow control characteristics. The butterfly valve has two sealing types: elastic soft seal and metal seal. Elastic soft seal valve, seal ring can be inlaid on the body or attached to the disc around. It uses PTFE seal, chemical corrosion resistance, high temperature and high pressure resistance.
Advantages of the wafer butterfly valve：
1.Good sealing performance
The media force of the butterfly wrench on both sides of the shaft is almost equal, the direction of the torque is opposite. Opening and turning off the torque is small, under low pressure, it can achieve good sealing.
2.Wide range of application
The structure principle of the wafer hard seal butterfly valve is especially suitable for the manufacture of large diameter valves. It is not only widely used in petroleum, natural gas, chemical industry, water treatment and other general industries, but also used in thermal power station cooling water system.
3.The whole body paint design
The body is usually made of overall paint, which can effectively prevent oxidation and rust.
The structure of the wafer butterfly valve is usually relatively small, and it has small operation torque and more efficient operation.
5.Ductile iron QT450-10 material
The body and disc material is ductile iron QT450-10 material, spheroidization rate more than 3 levels, the body and disc tensile performance is stronger, mechanical performance can meet the standards.
