Butterfly and obstruc valves
Description
Butterfly valves are used to maintain the unidirectional flow of liquid and to prevent reverse flow of the medium. Reservoir dampers, in turn, are used as control valve or shut-off. Flanged or wafer, with manual or automatic with electric actuator, hydraulic or pneumatic. Provided for a wide range of applications: water, wastewater, steam, gas. Butterfly valves of large diameter flanges are mainly used for water supply and sewerage networks.
