Principle Overview

Because the rotor of a valve is typically not in contact with the housing, continuous monitoring of the electrical signals between the rotor and housing indicates scratching when the rated value changes and a system alarm signal is generated through circuit conversion of the electrical signal.

Rotor Interference Detection

• High Processing Precision: Doebritz valves are well-designed to typically avoid scratching between on the rotor and the valve housing.
• High-strength structure. The valve features a high-tension design that enhances its stability. Foreign object impact The rotor may be scraped by foreign objects inside the valve
• Doebritz System: It is recommended to install a rotor scratch detection RID-system to monitor scratch conditions.
• Alarm mechanism: The Doebritz system issues an alarm when scratching occurs, prompting a shutdown to reduce the risk of damage.

Doebritz China is a joint-venture of Doebritz German and some expert in China powder handling industry with rich experience. The mission of the company is to provide high cost-performance product to the market. At the moment, 4 major products are the key. Dosing valves from Doebritz German, FG sifters from British, tipping station and integrated tipping station, coating and mixing system.
