Issues regarding the valve discs of gas valves
Thread Content
The compressor requires regular maintenance; can the valve plates be simply treated so as to be reused? The compressors in our company are frequently overhauled, and a large number of valve plates, gaskets, and other components have to be replaced each time, which seems really wasteful. Seafarers, come and share information about your companies and give your opinions.
The valve discs may seem simple, but the materials used are of high quality; it’s best to use those provided by the manufacturer to ensure safety. Moreover, considering the overall cost of the unit, the cost of the valve discs seems modest. If replacing them causes greater damage to the machine, it’s not worth it. It is recommended to use the manufacturer’s spare parts for such vulnerable components
The valve disc can be ground, and then the air valve can be assembled and tested for leaks by using water; if there are no leaks, it can be used again.
If there are no major issues with the valve disc, it can be turned over and used
The valve disc of Helbig can be used on both sides; it can be used by simply turning it around. I’ve used it!
It is necessary to check the degree of wear on the valve disc to determine whether it can be reused; if possible, it is better to replace it with a new one. Of course, good-quality valves do not necessarily require replacement. New valves come as complete units, and the valve discs and gaskets are not supplied separately
If the valve disc has no obvious cracks, radial grooves, or severe wear, it should be usable. But the prerequisite is to carry out grinding, and after assembly, a water test must be conducted to check its tightness before it can be used or kept in reserve.
In my workshop, the valve discs are removed for inspection, and if any signs of wear are seen, they are replaced :)
It’s better to replace it. It’s not worth it to cause an accident in the entire unit just because of a valve.
Grind the valve disc, assemble the air valve and check for leaks; it can be used if there are no leaks. But time has not grown any longer.
