Simple introduction
D671X pneumatic rubber clip butterfly valve product design is novel, reasonable, simple structure, small size, light weight, 90 degree rotation open and close quickly, operating torque is small, easy to operate, labor saving dexterity.It can be easily installed and maintained in any location.The sealing element can be replaced, and the sealing performance is reliable to achieve zero leakage of two-way sealing, the sealing material is resistant to aging, corrosion and long service life.
The disc thickness is the only resistance when the medium flows through the valve body, so the pressure drop produced by the valve is very small, so it has good flow control characteristics.Butterfly valve is not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of thermoelectric station.
