Are there any requirements regarding the location of the drain valve?

From our company, we observe that the drain valves are installed upstream of the control valves and flow meters? Are there any requirements for this? Most control valves are one-way valves

Inspection, cleaning, and evacuation usually need to be carried out upstream; control valves generally have an installation direction, but they are not one-way valves.

Got it. The key point is purging. Thank you
