Re: [PipingDesign] Query-Reduced Bore Ball Valves

BS 5331 and BS 5167 cover firesafe ball valves.

The size of the reduced bore is basically derived from the manufacturer. Use the valve losses to determine if you can accomodate these. The reduced bore is derived from the valve design where the aim is to keep the body small and thus reduce costs.
