Stainless Steel Pneumatic Butterfly Valves May Have Some Faults During Use
Sanitary Butterfly Valve is a common control valve, mainly composed of valve body, valve disc, sealing ring and drive device. It uses pneumatic actuator as the drive device, and uses compressed air to open and close the valve disc.
Stainless steel pneumatic butterfly valves may have some faults during use. The following are some common faults and their repair methods:
1. Leakage problem: If the butterfly valve is found to have leakage, first check whether the sealing ring is worn or damaged. If there is a problem, the sealing ring needs to be replaced or repaired. In addition, check whether the fastening bolts between the valve disc and the valve seat are loose. If loose, they need to be retightened.
2. The valve cannot be opened or closed: When it is found that the pneumatic butterfly valve cannot be opened or closed, you can check whether the drive device and sensor are working properly. At the same time, check whether the air source pressure is normal and whether there is any blockage at the pipeline connection.
3. Unstable operation: If the pneumatic butterfly valve shakes or vibrates during operation, it may be caused by unstable installation. The support structure can be adjusted or the support points can be added to solve this problem.
4. Abnormal air source pressure: If the air source pressure is found to be lower than the specified value, it may affect the normal operation of the butterfly valve. At this time, it is necessary to check the air supply system and ensure that sufficient compressed air is provided to the butterfly valve.
5. Leakage problem: During use, gas may leak from the joints or connections of the butterfly valve. This may be caused by loose joints or damaged sealing rings. It is necessary to check and tighten the joints and replace damaged sealing rings.
When repairing stainless steel pneumatic butterfly valves, be sure to ensure safe operation and perform repair work in accordance with the relevant equipment and material instructions. If the problem cannot be solved or professional technical support is required, please consult relevant professionals.
