Q971H-16P DN50 motorized stainless steel wafer ball valve AC380V

ball valve with electric actuator
Electric ball valve is a form of quarter-turn valve, it is characterized by well sealed, low resistance, compact structure, easy maintain, long service life. It perfect connects with pipe,  allow medium to flow without loss, is suitable for the field that required strictly for seal. Applicative medium like gas, liquid, water, steam and other fibrous material medium in sewage is ok for electric ball valve. It is widely used in food, pharmacy, cosmetics, clean steam, wine industry, beverage industry, chemical industry etc.

Electric Ball Valve is a rotary ball valve by turning 90°, with the characteristics of tine sealing performance, large flow capability, small flow resistant coefficient, simple structure and long service life. The valve passage is equal to the connecting pipe and the medium can nearly flow through it without the loss.
 
By connected with electric actuator the valve is widely applicable for the working fields such as petroleum, chemical, industry, metallurgy, paper making, power station etc. It can control not only the medium like the air liquid and steam, but also the medium containing the fibers.
