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. They are composed of
partial rotary electric actuators and wafer butterfly valve bodies.
Electric wafer butterfly valves for sewage can be used in occasions
with narrow space requirements and short pipeline distances on
site.
The butterfly valve body has no connecting rods, bolts, etc.,
featuring reliable operation, long service life, and multi-station
installation without being affected by the medium flow direction.
They are widely applied in dust-laden cold or hot air gas pipelines
for ventilation and environmental protection projects in industries
such as chemical, building materials, power stations, and glass,
serving as flow regulation or cut-off devices for gas media.
