I. Analysis of the Causes of Excessive Switching Torque of Ball Valves
(A) Problems with the Valve Body Structure
• Unreasonable Sealing Structure: Insufficient machining accuracy of the sealing surface or improper selection of sealing materials will lead to an increase in the friction between the ball and the valve seat, thereby increasing the switching torque.
In the field of industrial valves, DN300 trunnion ball valves are widely used, and different standards have their own specifications and requirements for wall thickness design. ASME B16.34 and DIN 3357, as two standards that attract much attention internationally, understanding the differences in wall thickness design between them plays a crucial role in correct selection, ensuring the performance and safe use of ball valves. Next, we will conduct an in-depth analysis of the differences in wall thickness design of DN300 trunnion ball valves under these two standards and provide corresponding selection guidelines.
