Purpose and features：
The BR.W84 series pneumatic eccentric rotary control valve (also known as cam deflection valve) adopts Masoneilan technology combined with the characteristics of China, and combines the advantages of single seat valves, ball valves, butterfly valves, etc. It has outstanding advantages such as simple structure, small volume, light weight, large rated flow coefficient, large adjustable range, wide temperature range, small leakage, and good stability. Due to the fact that the plug and stem only rotate, the friction force they experience during operation is very small. When the plug and seat are in contact and closed, the plug deflection arm generates small elastic deformation and elastic tightening force under the thrust of the executing structure, making the contact between the plug and valve seat more tight and firm. Therefore, the leakage of the eccentric valve is very small. The actuator thrust required to close the valve is smaller than that of ball valves and butterfly valves. Therefore, this series of products is widely used in automatic control systems for industrial processes such as chemical, metallurgical, and power plants.
