Are there any specific specifications for the valve cylinder and the valve seat bracket?
Thread Content
Are the dimensions of the brackets between the valve cylinder and the valve seat determined according to each brand’s own specifications, or is there a standard? If the valve bracket of a certain brand breaks, should one purchase a replacement from the market or have it custom-made by the original manufacturer? Also, if metal sheets are to be added in the middle of the filler, are there any specific regulatory requirements for this?
I’m not sure which specific standard it is, but one does exist
The regulations only set out a principle; as for the specific design, one can calculate it themselves or rely on experience – simplicity, low cost, and practicality are what matter
