Tapered Plug Valve
Tapered Plug Valve
(OP)
Does anyone know how metal to metal tapered plug valves are manufactured to create a proper seal (For use on LP, per ANSI Z21.15). Do the plug and body need to be lapped into eachother, should the body be ground, or can close tolerance machining centers provide the required finishes. Thanks.

Also how could the plug move inside the body taper bore if these angles are different baffles me.
