The pressure class of the valve body at 20 °C. Working limits depend on the medium and its temperature.
Construction
Parts and materials
The WBV1632E-2W-Fb butterfly valve is designed for use as shut-off or regulating valves for flow control in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries. Operating principle: The valves are opened and closed by turning the disk by 90°. Opening is performed by turning the handle counterclockwise, closing - clockwise.
PA-SA pneumatic actuators are designed for automation of control process of industrial shut-off valves - gates, ball valves. Pneumatic actuators are designed for operation both indoors and outdoors. All internal and external parts are anticorrosive coated.
