Construction
Parts and materials
DNOVA WBV1132N-2W-Fb-H butterfly valves 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 the direction, start, stop the compressed air flow in the pneumatic system depending on the external control action.
The DNOVA APL-210N EX limit switch unit is an electrotechnical device designed to open and close the working circuit and to visualise the positions of the shut-off body 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 signalise extreme positions. They are mounted on top of the actuator surface. In the upper part of the limit switch unit there is a two-coloured visual indicator hemisphere. If the connected pipe fitting is closed, only the red part of the hemisphere labelled CLOSED is visible; if it is open, only the yellow part labelled OPEN is visible. This visual indicator is clearly visible from a distance, which simplifies the inspection of the equipment, and the colour difference between open and closed position reduces the probability of misinterpretation of information. Thanks to the use of the BCV it becomes 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 fault detection.
The DNOVA MON manual doubleturn actuator with worm gear and HDM reduction reducer enables 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.
