This valve is widely used in the pipe system such as venting and environment protection in building material, glass, mining, power, light industry and papermaking departments. It can change the flow and cut off gas medium in the pipe by the different control signal. The valve has the features of lightweight, compact structure, endurance, little in the lost of flow resistance, high working pressure, flexible operation, definite direction, easy to maintenance and long life. It can be installed at any angle. It is suitable in the condition of adjusting, cutting off and self-protecting quickly. The valve is used with DKJ, ZKJ, Bernard electric actuator and other accessory to form a complete set to realize manual and automatic exchange without interference, micro-computer long-range control, automatic control or center concentrating control. It is the ideal equipment of realizing operation of automatic control and adjusting flow.
Butterfly valve is closed a disc, around the axis of rotation to achive a valve open and close, in the tube on the main cuttring and throttling. Opening and closing is a disc-shiped buttefly plate, the body is around its own axis rotation turn, so as to achieve the aim of opening and closing or adjust. Buttefly valve fully open to the barrier is usually less than 90c, butterfly valve and the adjusment rod itself-locking ability, for the sake of the butterfly plate positioning, to add worm gear reducer on the valve stem, the use of worm gear reducer, can not only make the butterfly plate with self-locking ability. Make the butterfly plate to stop at any position, can also improve the operating performance of the valve.
