The FR series pneumatic eccentric rotary regulating valves , are used in automatic control systems for industrial processes such as chemical engineering , metallurgy , and power stations

The FR series pneumatic eccentric rotary regulating valve, also known as the cam flexing valve, combines the technology of Messer Nieland with the characteristics of our country. It integrates the advantages of single-seat valves, ball valves, and butterfly valves, featuring a simple structure, small size, light weight, large rated flow coefficient, wide adjustable range, wide operating temperature range, low leakage, and good stability. Due to the fact that the valve core and stem only undergo rotational movement, the friction force during operation is very small. When the valve core and seat come into contact to close, the valve core flex arm produces a slight elastic deformation and elastic clamping force
under the thrust of the actuating mechanism, making the contact between the valve core and seat more tight and secure. Therefore, the leakage of the eccentric valve is very small. At the same time, the actuating mechanism thrust required to close the valve is smaller compared to that of ball valves and butterfly valves. Consequently, this series of products is widely used in industrial process automation control systems such as chemical, metallurgical, and power plants.
