Parts and materials
Butterfly valves DNOVA WBV3232N-2W-Fb-H are intended for use as shut-off or control valves for flow control in heat supply systems, water supply, in technological processes of food, chemical, oil and gas, pulp and paper and other industries.
Pneumatic distributor DNOVA 4V320-08 220V is used to change the direction, start, stop the flow of compressed air in the pneumatic system depending on the external control action.
The AFC2000 air preparation unit is designed to clean compressed air from droplet moisture and solid particles, remove condensate, automatically maintain the pressure at a given level, supply lubricant from the tank to the compressed air flow to the pneumatic system elements with a large range of throughput from 500 liters/minute to 10,000 liters/minute. The lubricator (oil sprayer) 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 distributors.
