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. The valves are opened and closed by turning the disk by 90°. Opening is performed by turning the handle counterclockwise, closing - clockwise.

Pneumatic rotary actuators with return spring PA-SA are designed for automation of industrial valve control with maximum torque up to 2128 Nm.

The limit switch unit is an electrical device designed to open and close the working circuit and to visualize the positions of the shut-off body of the pipeline valve. 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. Due to the use of the BCV it becomes possible to transmit information on the position of pipeline valves (open/closed) to automated control systems, which allows to increase the reliability of the system as a whole and simplifies diagnostics in case of fault detection.
