Pneumatic control valves are now widely used, with a wide variety of valve types. However, we need to be prepared during use. Let's take a look at the maintenance and installation principles of pneumatic control valves together with New Europe!
Malfunctions of pneumatic control valves during use can pose a significant threat to the normal and stable operation of the system. Therefore, maintenance of the control valves is required to reduce the incidence of valve failures.
1. Passive maintenance of pneumatic control valve
When the pneumatic control valve malfunctions, it is necessary to conduct maintenance on the control valve, identify the cause of the malfunction, and carry out timely repairs.
2. Preventive maintenance of pneumatic control valve
Regular cleaning should be carried out on the regulating valve to maintain its hygiene and the integrity and durability of all components. The pipeline should be flushed regularly, and attention should be paid to blockages and debris in the pipeline. The fixed fittings of the regulating valve should be inspected regularly to ensure good anti-corrosion and lubrication performance of the components.
When installing pneumatic control valves, reduce the phenomenon of hard pulling and bending during installation, lower pressure, and minimize deformation. Maintain the distance between the regulating valve and the compressor to reduce vibration from the vibration source. Regularly inspect the regulating valve, closely monitor its operation, check for any leaks in the packing, and regularly add lubricating oil to the packing.
3. Predictive maintenance of pneumatic control valve
By using intelligent instruments or other diagnostic devices to obtain operational information of the regulating valve, the regulating quality and diagnostic function of the regulating valve can be enhanced. Through the diagnosis of intelligent instruments or other diagnostic devices, problems with regulating valves can be detected in a timely manner, and solutions can be found for maintenance. Increase the development and use of intelligent valve positioners.
