Construction
Parts and materials
DNOVA WBV3232E-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.
The DNOVA 4V320-08 220V pneumatic valve is used to change the direction, start and stop the compressed air flows in the pneumatic system depending on the external control action.
Air treatment unit AFC2000 is designed to clean compressed air from dripping moisture and solid particles, condensate removal, automatic maintece of pressure at a preset level, supply of 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.
