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 valves control process 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 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. They are designed for use with quarter-turn pneumatic actuators.
