Valve sizing often is described by the nominal size of the end connections, but a more important measure is the flow that the valve can provide. And determining flow through a valve can be simple.
Welding should be done by qualified personnel as outlined in Section IX of the ASME Boiler Code. Weld filler material should be the same as the base material.
