Parts and materials
Butterfly valves DNOVA 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.
Pneumatic valve DNOVA 4V320-10 220V is used to change direction, start, stop compressed air flows in a pneumatic system depending on external control action.
Manual doubler DNOVA MON with worm gear and HDM reduction gearbox allows to manually set the required positioning of the shut-off valve by a quarter turn, acting as an alternative to pneumatic, electric or hydraulic quarter-turn actuators. Suitable for both indoor and outdoor installation. The modular design of the manual doubler is intended to provide the most effective and efficient solution to the full range of manual override applications.
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.
