    Hi,
    I am working as a design engineer. I am new to pressure seal bonnet Valve design. In that valve concept we are using a ring called as Segmental ring. The purpose of this ring is to withstand the entire force acting on the bonnet due to is working pressure. Now i want to know how to calculate the thickness of that ring. Here i am attaching the Picture for your ref. Thanks in advance.

    Is this for a reciprocating or a rotating shaft?
    Is it for air, steam or some other fluid?
    What is the maximum operating pressure and temperature?

    In your section diagram 10e.jpg I see no contact between a moving shaft and a seal that will wear. It appears to only involve a static packing. So where is your segmental seal going to be placed?
