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.

PA-DA double-acting pneumatic rotary actuators are designed to automate the process of controlling industrial valves with maximum torque up to 2128 Nm.

Pneumatic valves are used for control in pneumatic systems with NAMUR docking surface, for installation of valves through through holes in the body. Electromagnetic control, is realized by means of voltage coils 12-AC, 12-DC, 24-AC, 24-DC, 110-AC, 220-AC. Depending on the model, the valves have one-way or two-way control. Solenoid operated pneumatic valves have a wide range of models and include common switching types for three (3/2) and five (5/2 and 5/3) line pneumatic valves. Designed for use with quarter-turn pneumatic actuators.

The HDM worm gear reduction manual doubler allows manual adjustment of the required positioning of the shut-off valve by a quarter turn, acting as an alternative to pneumatic, electric or hydraulic quarter-turn actuators. Suitable for both indoor and outdoor installation. The modular design of the manual override is intended to provide the most effective and efficient solution to the full range of manual override applications.

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 a 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. Thanks to the use of the ACB it becomes 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.

The air treatment unit is designed to clean compressed air from moisture and solid particles, remove condensate, automatically maintain the pressure at the preset level, supply lubricant from the tank in the compressed air flow to the pneumatic system elements.
