A wedge pin for a butterfly valve provides a secure, mechanical connection between the valves shaft (stem) and the disc. In high-performance, double-offset, and triple-offset butterfly valves, this wedge pin design reduces stress on the shaft and ensures a backlash-free, reliable transmission of force for maximum service life.
Purpose and function
Disc-to-shaft connection: The primary function of the wedge pin is to attach the disc to the stem, which transmits the rotational force from the actuator to open and close the valve.
Positive mechanical attachment: It provides a strong, positive lock that prevents slippage or movement between the shaft and disc, even under high torque and stress.
Reduced stress: By offsetting the pin from the center of the stem, the tangential wedge pin places the load in compression rather than shear. This dramatically lowers the stress concentration on the shaft compared to older designs, increasing the joints overall strength.
Backlash-free operation: The wedge shape and precision fit of the pin and its connection ensure a permanently tight, backlash-free joint, which is crucial for reliable and consistent valve operation.
Enhanced durability: This robust connection method prevents wear and tear on the shaft and disc, contributing to a longer valve service life.
