Electric flange butterfly valve
Simple introduction
D941X electric flange soft seal butterfly valve product design, reasonable, simple structure, small volume, 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.
Flange butterfly valve at the full open position, butterfly plate thickness is the only resistance of medium flow through the valve, 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 thermal power stations.
