There may be several reasons why the electric butterfly valve does not close properly:
OneThe actuator of the electric butterfly valve is faulty:
There may be faults in the actuator, such as unstable motor speed, damaged gears, etc., resulting in the butterfly valve not being able to close completely.
IITransmission component failure:
The transmission components of the electric butterfly valve, such as the transmission shaft and the transmission rod, may be faulty, resulting in the butterfly valve not being closed properly.
IIIButterfly valve seal failure:
The seals of butterfly valves may have problems such as wear and age, which may prevent them from closing completely.
FourthControl System Failure:
The control system of the electric butterfly valve may have faults, such as sensor failure, abnormal control signal, etc., resulting in the butterfly valve not being able to close normally.
FiveInterference from external factors:
External environmental factors, such as temperature changes, pressure changes, media foreign objects, etc., may interfere with the closing of the butterfly valve, making it impossible to close completely.
To sum up, the reasons for the failure of the electric butterfly valve to close may involve the failure of the actuator, the failure of transmission components, the failure of the butterfly valve seal, the failure of the control system and the interference of external factors. When troubleshooting, you need to check these possibilities one by one and take corresponding corrective measures.
