Reference Standards API 6D - Specification for Pipeline Valves. API 598 - Valve Inspection and Testing/ API 608 - Metal Ball Valves - Flanged, Threaded and Welding Ends ASME B16.5 - Pipe Flanges and Flanged Fittings. ASME B16.10 - Face-to-Face and End-to-End Dimensions of Valves. ASME B16.25 - Buttwelding Ends. ASME B16.34 - Valves – Flanged, Threaded, and Welding End. ASME B16.47 - Large Diameter Steel Flanges.

Advantage of Trunnion Ball Valve: With trunnion ball valve, the ball is anchored at the top and bottom. Whereas for floating ball valve, the ball in only anchored at the top. Hence, for trunnion ball valve, the ball movement is better aligned, which is very important for higher pressure rating and larger sizes.
