KHB Ball Valves/KHB3K Ball Valves Factory introduces the precautions for maintaining the regulating valve:
1. The purpose of use and maintenance is to extend the life of the pneumatic control valve and ensure reliable opening and closing.
2. The valve stem thread is often rubbed with the valve stem nut, and a little yellow dry oil, molybdenum disulfide, or graphite powder should be applied to lubricate.
3. Pneumatic control valves that are not frequently opened and closed should also turn the handwheel regularly, and add lubricant to the valve stem threads to prevent biting.
4. For outdoor pneumatic control valves, a protective cover should be added to the valve stem to prevent rain, snow, dust, and rust.
5. If the pneumatic control valve is mechanically ready to act, add lubricating oil to the gearbox on time.
6. Always keep the pneumatic control valve clean.
7. Always check and maintain the integrity of other parts of the pneumatic control valve. If the fixing nut of the handwheel falls off, it must be matched and cannot be used properly, otherwise, it will grind the square on the upper part of the valve stem, gradually lose the reliability of cooperation, and even cannot be started.
8. Do not rely on the pneumatic regulating valve to support other heavy objects, and do not stand on the pneumatic regulating valve.
9. The valve stem, especially the threaded part, should be wiped frequently, and the lubricant that has been soiled by dust should be replaced with a new one, because the dust contains hard debris, which is easy to wear on the surface of the thread and valve stem, affecting the service life. Seat control valve.
