Electric butterfly valve

Short Description:

The design of electric butterfly valve is novel, reasonable, simple in structure, small in volume and light in weight. The 90-degree turning is quick to start and close, small operating moment, easy to operate and dexterous. It can be installed at any position, easy maintenance, replacement of seals, reliable sealing performance to achieve two-way sealing zero leakage, aging resistance of sealing materials, corrosion resistance, long service life and so on.

When the rubber butterfly valve is in full open position, the butterfly plate thickness is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics. Butterfly valves are 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 plants.
