Automatic Actuation Electric Butterfly Valve for General Applications
Highlight: Electric butterfly valve
Product introduction:
The sealing types of electric wafer butterfly valves for sewage are divided into several forms: triple-eccentric metal-sealed
electric wafer butterfly valves, hard-sealed electric wafer butterfly valves, soft-sealed electric wafer butterfly valves, center-
line soft-sealed electric wafer butterfly valves, and double-eccentric soft-sealed electric wafer butterfly valves. Composed
of partial rotary electric actuators and wafer-type butterfly valve bodies, these valves are suitable for occasions with narrow
site space and short pipeline distances. The butterfly valve body features no internal linkages or bolts, ensuring reliable
operation and long service life. It allows multi-station installation without being affected by the medium flow direction. Widely
applied in ventilation systems of chemical, building materials, power stations, glass industries, and dust-laden cold/hot gas
pipelines for environmental protection projects, they function as flow regulation or shut-off devices for gaseous media.
