How it works
Double-acting rotary actuator
Butterfly disc
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
The butterfly valve is designed for use as shut-off or regulating valves for flow control in heat and water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries. Butterfly valves should be installed only between collar flanges.
PA-DA-105-1 double-acting pneumatic rotary actuators are designed for automation of industrial valves control process at maximum torque up to 2128 Nm.
