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 supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries.
Pneumatic double-acting rotary actuators PA-DA and pneumatic rotary actuators with return spring PA-SA are designed for automation of industrial valve control process with maximum torque up to 2128 Nm.
The pneumatic valve is used to change the direction, start, stop the compressed air flow in the pneumatic system depending on the external control action.
The limit switch unit is designed for visual and electrical signaling of the end positions of the shut-off body of the pipeline valve.
