The bolt stress upon the gasket must also overcome hydrostatic forces generated by internal fluid or gas pressure as well as torque and vibrations encountered during normal usage. This design seating stress has been given the term y (yield) factor, and it is the stress required to deform the gasket into the irregularities of the joint surface. Suggested Action Consult with a veterinarian to have teeth trimmed regularly. Calculate gasket winding area, forget "b", just use pi/4 * (OD^2 - ID^2). The block-and-bleed and double block-and-bleed capabilities are available as per API 6D definition on all types of B4 valves.
