Description
The butterfly valve is designed to be used as a shut-off or control valve to control flows in heat supply systems, water supply, in technological processes in the food, chemical, oil and gas, pulp and paper and other industries. Operating principle: The valves open and close by turning the disk 90°. Opening is done by turning the handle counterclockwise, closing - clockwise.
DNOVA pneumatic rotary actuators double-acting PA-DA-XXX and pneumatic rotary actuators with return spring PA-SA-XXX are designed to automate the process of controlling industrial valves at a maximum torque of up to 2128 Nm.
