Maintenance and use of pneumatic butterfly valve

Pneumatic control butterfly valve is an automatic control valve composed of pneumatic actuator and butterfly valve. Pneumatic valve has the advantages of fast driving speed, safety, cleanness and low failure rate. Pneumatic actuator is usually made of aluminum alloy with anodizing treatment on its surface. It is corrosion-resistant and oxidation resistant, and has a long service life. Of course, no matter how good a product is, it needs to know how to maintain it so as to maximize its performance.


In the maintenance of pneumatic butterfly valve, pay attention to the following points:

1、 When the working condition and environment meet the use requirements, waterproof measures shall be taken to prevent impurities such as waterproof and oil from penetrating into the actuator or valve, so as to shorten the service life of the valve. Regular maintenance, add lubricating oil or remove surface dirt and dust.


2、 If it needs to be disassembled, pay attention to protect the sealing surface of the valve body to prevent collision, scratch, etc. from affecting the sealing performance. In case of abnormal fault and abnormal operation, the gas source and medium should be cut off to find out the cause. It can be used after normal test.


3、 If not used for a long time, also pay attention to storage conditions, it is best to place in a ventilated and dry place. In order to avoid damage caused by long-term moisture.
