Hello sagar ,
So the valve has to be installed with respect to PPE not by flow direction ie. If the flow as per iso is east to west and when the valve is installed with respect to PPE the flow for valve is west to east and it doesn't matters ?? Is there a document or standard which gives detail explanation about PPE ???

Orbit valves are single seated valves; this arrangement make the valves unidirectional.
Manufacturers of these valves mostly mark PPE on flange rims instead of flow directions.
