Construction
Parts and materials
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 having 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 efficient and effective solution to the full range of manual override applications.
The air treatment unit is designed to clean compressed air from dripping moisture and solid particles, remove condensate, automatically maintain the pressure value at a preset level, supply lubricant from the reservoir in the compressed air flow to the pneumatic system elements.
