1. Sealing surface leakage Cause of the fault: Impurities are embedded in the sealing surface of the butterfly valve, the sealing surface is damaged, and the sealing surface is improperly installed, resulting in uneven force on the sealing surface. The seal is aged and damaged. Solution: Clean up the impurities on the sealing surface to
A check valve, also known as a non-return valve, one-way valve, or isolation valve, is a valve that automatically opens and closes its valve disc based on the flow of the medium itself. Its primary functions are to prevent the reverse flow of the medium and the reversal of pumps and driving motors, thereby protecting
How to Determine if an Electric Butterfly Valve Needs Replacement? I. Leakage Conditions There is evident leakage of the medium within the valve body, whether through the valve stem, valve seat, or the connection between the valve body and the pipeline. If the leakage issue cannot be effectively resolved even after multiple repairs and adjustments,
