High performance sealing butterfly valve
High performance sealed butterfly valves are widely used in ventilation and other pipeline systems in industries such as building materials, glass, mining, power, light industry and papermaking to adjust the flow rate and cut off the gas medium in the pipeline according to different control signals.
High performance sealed butterfly valves have the advantages of light weight, compact structure, small flow resistance loss, high working pressure, large sealing pressure difference, flexible operation, clear indication direction, convenient maintenance and long service life. It can be installed at any angle, especially suitable for adjusting, cutting and situations requiring quick self-protection. Equipped with electric actuators such as DKJ, ZKJ, Bernard, and related accessories, it can achieve manual and automatic interference-free switching, microcomputer program control, automatic control, or centralized control. It is ideal equipment for achieving automatic control operation and flow regulation.
