Description
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.
PA-DA double-acting pneumatic rotary actuators and PA-SA pneumatic rotary actuators with return spring are designed for automation of industrial valve control process with maximum torque up to 2128 Nm.
The electropneumatic rotary positioner is used for controlling pneumatic rotary actuators by means of an electric controller or control system with analog DC output signal range from 4 to 20 mA.
Operating principle: The positioner functions based on the balancing of forces. The positioner uses a nozzle-flap type device and a feedback servomechanism (a system of springs and levers) to balance the control and feedback forces when the pneumatic actuator (valve) reaches the position corresponding to the control signal.
The HDM worm gear manual doubleturn actuator with reduction gearbox allows the manual setting 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.
