Butterfly valves are designed for use as shut-off or regulating valves for controlling flows in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries. Operating principle: The valves are opened and closed by turning the disk by 90°. Opening is performed by turning the handle counterclockwise, closing - clockwise.
Pneumatic DNOVA pneumatic double-acting rotary actuators PA-DA and pneumatic rotary actuators with return spring PA-SA are designed for automation of industrial valves control process with maximum torque up to 2128 Nm.
Pneumatic valves are used to change the direction, start, stop the compressed air flow in the pneumatic system depending on the external control action.
Limit switch unit is an electrical device designed for opening and closing of the working circuit and for visualization of the positions of the shut-off body of pipeline valves. In a sealed box, as a rule, there are two mechanical switches designed for voltage up to 250 V, which monitor the position of the actuator stem and signalize in extreme positions. They are mounted on top of the actuator surface. In the upper part of the limit switch unit there is a two-color visual indicator hemisphere. If the connected pipe fitting is closed, only the red part of the hemisphere labeled CLOSED is visible; if it is open, only the yellow part labeled OPEN is visible. This visual indicator is clearly visible from a distance, which simplifies the inspection of the equipment, and the color difference between the open and closed position reduces the probability of misinterpretation of information. The use of limit switch units makes it possible to transmit information on the position of pipeline valves (open/closed) to automated control systems, which increases the reliability of the system as a whole and simplifies diagnostics in case of malfunction detection.
Air treatment unit is designed to purify compressed air from moisture droplets and solid particles, remove condensate, automatically maintain pressure at the set level, supply lubricant from the tank in the compressed air flow to the elements of the pneumatic system.
