Parts and materials
Butterfly valves DNOVA WBV3131P-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 the direction, start, stop the compressed air flow in the pneumatic system depending on the external control action.
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.
