The number that matters
Nominal pressure
16bar
The pressure class of the valve body at 20 °C. Working limits depend on the medium and its temperature.
Construction
Parts and materials
GGG50-GGG40-EPDM butterfly valve is designed for installation on pipelines in automatic control systems of heat and water supply, in stationary air conditioning and ventilation systems at industrial and civil facilities.
Pneumatic actuators PA-DA-105-1 double-acting rotary actuators are used for automation of industrial valves control process with maximum torque up to 2128 Nm. Adjustment range - 5° when the valve stem is rotated by 90° degrees. Operating environment: indoors and outdoors. (All internal and external parts are anti-corrosion coated).
