How to improve the service life of self-operated regulating valve and prevent damage?
After the self-operated control valve is assembled and painted, and the actuator, handwheel, positioner and other accessories are installed as required, in order to prevent foreign substances from entering the self-supporting control valve, all air ports connected to the self-supporting control valve must be blocked. Install the protective cover on the flange, and pay attention to the status of each connection part, such as the valve positioner intake pipe and the actuator interface. Any protruding accessories that are susceptible to damage, such as pressure gauges for oilers and potentiometers, should be removed from the fittings, packaged separately from the self-supporting regulator, and shipped together. The self-operated control valve should be fixed with a special bracket to prevent loosening, and the overall vertical or horizontal position should be guaranteed. If it is transported over long distances, it is better to use a sturdy wooden box.
When storing the self-operated control valve, do not support the self-operated control valve on sensitive parts, such as valve positioners, valve stems, etc. The environmental conditions for transportation and storage should meet the requirements of the product specification. It is better not to carry out other operations in the storage area. When it is unavoidable, you must be careful not to touch the self-supporting control valve. The place should also avoid being affected by harsh conditions such as sand, dust, rain, etc. If there is no suitable place, the self-operated regulating valve must be installed in a moisture-proof bag or a similar container before storage.
