Product Details

The product description

D943 type electric butterfly valve is through the circular disc plate with the valve rod rotation as open-close, open or close the valve, butterfly valve is mainly for the use of block valves, can also be designed to have the function of regulating and truncation. Valves electric actuator save a lot of manpower and opening closing time. Triple eccentric multi-level butterfly valve has no mechanical wear and tear, can reach zero leakage, suitable for petroleum, chemical industry, metallurgy, electric power, food, medicine, on different medium such as water supply and drainage, gas transmission pipeline as the adjusting and the best device to cutting fluid.
