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 and pneumatic rotary actuators with return spring PA-SA are designed to automate the process of controlling industrial valves at a maximum torque of up to 2128 Nm.
The pneumatic distributor is used to change the direction, start, stop compressed air flows in a pneumatic system depending on the external control action.
The air preparation unit is designed to clean compressed air from droplet moisture and solid particles, remove condensate, automatically maintain pressure at a given level, and supply lubricant from the reservoir to the compressed air flow to the elements of the pneumatic system.
