Butterfly valve WBV0232E-2W-Fb-H with pneumatic double-acting actuator

Butterfly valves DNOVA are designed for use as shut-off or regulating valves for flow control in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries.
Pneumatic valve DNOVA 4V320-10 220V is used to change direction, start, stop compressed air flows in pneumatic system depending on external control action.
DNOVA APL-410N EX limit switch unit is an electrotechnical device designed to open and close the working circuit and to visualize the positions of the shut-off device of pipeline valves. 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. The use of limit switch units makes it 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 DNOVA MON manual doubler with worm gear and HDM reduction gearbox allows to manually set 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 doubler is designed to provide the most effective and efficient solution to the full range of manual override applications.
