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 to control flows in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries.
DNOVA double-acting pneumatic actuators PA-DA-105-1 are designed for automation of industrial valves 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.
