Construction
Parts and materials
Butterfly valves DNOVA are designed for use as shut-off or regulating valves for flow control in heat and water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries.
Pneumatic distributor DNOVA 4V320-10 220V is used to change direction, start, stop compressed air flows in pneumatic system depending on the external control action.
The AFC2000 air treatment unit is designed to purify compressed air from dripping 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 elements with a large capacity range 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.
