The butterfly valve is designed to be used as a shut-off or control valve for flow control in heat supply systems, water supply, in technological processes in the food, chemical, oil and gas, pulp and paper and other industries. Operating principle: The valves open and close by turning the disk 90°. Opening is done by turning the handle counterclockwise, closing - clockwise.
DNOVA pneumatic rotary actuators double-acting PA-DA-XXX and pneumatic rotary actuators with return spring PA-SA-XXX are designed to automate the process of controlling industrial valves at a maximum torque of up to 2128 Nm.
Pneumatic distributors are used for control in pneumatic systems with a NAMUR mating surface, for installing distributors through through holes in the body. Electromagnetic control is carried out using voltage coils 12-AC, 12-DC, 24-AC, 24-DC, 110-AC, 220-AC. Depending on the model, the distributors have one-way or two-way control. Pneumatic distributors with electromagnetic control have a wide range of models and include common types of switching for three (3/2) and five (5/2 and 5/3) linear pneumatic distributors. Intended for use with quarter-turn pneumatic actuators.
The limit switch unit is designed for visual and electrical signaling of the end positions of the shut-off element of the valve: valve, tap or butterfly valve. It is installed on top of the surface of the pneumatic actuator and connected to the DIN standard actuator shaft. As a rule, there are two sensors in a sealed box that monitor the position of the actuator shaft and signal in extreme positions. OMRON microswitches, inductive sensors or reed switches are used as sensors.
