Parts and materials
Butterfly valves DNOVA WBV3432P-2W-Fb-H are designed for use as shut-off or regulating valves to control flows 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.
The DNOVA APL-210N limit switch unit is an electrotechnical device designed to open and close the working circuit and to visualize 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 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. By using the AFC2000, it becomes possible to transmit information on the position of the 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 AFC2000 air treatment unit is designed to clean compressed air from moisture droplets and solid particles, remove condensate, automatically maintain pressure at a preset level, supply lubricant from the tank in the compressed air flow to the elements of the pneumatic system with a wide range of throughput from 500 liters/minute to 10 000 liters/minute. The lubricator adds oil with a viscosity of 32 mm²/s (=cSt) at 40°C to the pneumatic system for further lubrication of control components such as pneumatic cylinders and pneumatic valves.
