Troubleshooting of leakage at both ends of electric butterfly valve. 1. Electric butterfly valves on both sides fail. 2. The tightening force of pipe flange is uneven or not compacted. 3. The upper and lower sealing gaskets of the sealing ring are invalid.

In addition, the sealing of pneumatic butterfly valves is best performed at low air pressure, so we need to adjust the standard air pressure in the workplace. On the other hand, the hydraulic control system should be in the closed direction during the period of our equipment pneumatic butterfly valve to avoid potential safety hazards after the route is connected. During the maintenance period of the electric butterfly valve, we should also try our best to keep all machinery and equipment in a natural and ventilated environment, so as to avoid excessive vegetable grease and dirt blocking the pipeline of the pneumatic butterfly valve, which will greatly harm the efficacy and efficiency of all machinery and equipment.
