Description
Ball valve DNOVA BV3232P(2pc)-FP-F-ISO-H is used as a shut-off valve in heat supply systems, water supply systems, in steam, fuel and pneumatic systems with compressed air and neutral gases. Installation of BV3232P(2pc)-FP-F-ISO-H series valves is possible in systems transporting liquid and gaseous media (water, oil, oils, steam, air, alcohols, glycol, etc.) that are not aggressive to valve materials.
Pneumatic actuator DNOVA PA-SA with return springs is designed for automation of control process of industrial shut-off valves - gates, ball valves. DNOVA pneumatic actuators are designed for operation both indoors and outdoors. All internal and external parts are anticorrosive coated.
Pneumatic valve DNOVA 4V320-08 220V is used to change direction, start, stop compressed air flows in pneumatic system depending on external control action.
The DNOVA APL-410N EX limit switch box is an electrical device designed to open and close the working circuit and to visualise the positions of the shut-off valve body. 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 allows to increase 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 and solid particles, remove condensate, automatically maintain pressure at a preset level, supply lubricant from a reservoir in the compressed air stream to pneumatic system components with a large capacity range from 500 litres/minute to 10,000 litres/minute. The lubricator (oil atomiser) adds oil with a viscosity of 32 mm²/s (=cSt) at 40°C to the pneumatic system for further lubrication of control components - pneumatic cylinders and pneumatic valves.
