Brief Introduction
D671X pneumatic wafer rubber butterfly valve has novel and reasonable design, simple structure, small size, light weight, quick opening and closing of 90-degree rotation, small operating torque, easy operation, labor-saving and dexterous. It can be installed in any position and is easy to maintain. The seal can be replaced, and the sealing performance is reliable to achieve two-way sealing and zero leakage. The sealing material is resistant to aging and corrosion, and has a long service life. When the wafer rubber butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body. Therefore, the pressure drop generated by the valve is very small, so it has good flow control characteristics. Butterfly valves are not only widely used in general industries such as petroleum, gas, chemical industry, and water treatment, but also in the cooling water system of thermal power plants.
