Sanitary Butterfly Valve Issues that require special attention

No matter what valve it is, leakage may occur during use, and leakage is a very serious problem for valves, so special attention should be paid to valve leakage, and the same is true for ventilation butterfly valves.

Electric ventilation butterfly valves are made of steel plate welding, and the connection between the valve and the actuator is directly connected. The electric actuator does not need to be equipped with a servo amplifier, and the input of 220VAC power supply can control the operation. Some people may not know the leakage problem until they are in use, which is very troublesome. We can do some work to prevent leakage of ventilation butterfly valves. For example, before use, you must carefully test the pressure and leak. If you find leakage on the sealing surface or at the root of the sealing ring, you must deal with it before use; check whether the various components of the ventilation butterfly valve are intact in advance, and do not use valves with bent stems or unreliable connections between the valve disc and the valve stem, etc.
