First make up your mind:

• You Want " how to get ASME f 1565 and ASME 16.34" OR
• You Want " design contol valve and pressure reducing"

Come back to CR4 with full problem statement if you want to Optimally Design/select Control Valve for a particular application of pressure Reduction.

Go to ASME-USA -- for ASME's codes.

Cheers

The following codes & standards are related to valves & control valves :

ASME B16.34 Valves-Flanged, Threaded, and Welding Ends.

ISA RP75.06 Control valve manifold designs recommended practice.

ISA RP75.03 Face-to-face dimensions for flanged globe-style control valve bodies (ANSI classes 125, 150, 250, 300 & 600).

ISA RP75.04 Face-to-face dimensions for flange less control valve bodies (ANSI classes 150, 300 & 600)

(ASME: American Society of Mechanical Engineers & ISA: Instruments Society of America)
