For answer to your query regarding straight length requirement for swing check valves (and some other useful information too), you may like to refer:

1. BS 6683: Valves, Installation and Use
2. MSS SP-92: MSS Valve User Guide

Subject: [PipingDesign] querry....

Can any one please tell the required straight upstream and downstream requirement for Restriction Orifice? Please note that this orifice is only
for pressure drop purpose and not for flow measurement. What could be the
reason for this requirement?

Has anyone come across the straight length requirement for check valves, especially swing check valves? Why is this needed?

Request members to throw some light on this.

Regards

Vaibhav Devdhar
