Product description
D943 electric butterfly valve is through the rotation of the circular plate with the stem for opening and closing parts to achieve the valve open or closed, the main valve for the use of cut-off valve can also be designed to have the function of regulation and truncation. Valve configuration electric actuator to save a lot of manpower and turn off time. Three eccentric butterfly valve multi-level has no mechanical wear, up to zero leakage for as regulation, cut off fluid and the best device in petroleum, chemical, metallurgy, electric power, food, medicine, to drainage, gas transportation and other different medium pipeline.
