THREADED END VALVES – END TO END AND CENTRE TO END DIMENSIONS – NEW STANDARD ISSUED BS EN16722:2015

What is it?: BS EN 16722 specifies the end-to-end and centreto- end dimensions for gate, globe, lift check and ball valves with threaded ends with connecting dimensions in compliance with EN ISO 228-1 or EN 10226-1, used in PN and Class designated piping systems.

Why is it important?: This is a new standard. Its scope includes valves sizes DN4 to DN100 in pressure designations PN10 to PN400 and Class 150 to Class 2500. In practice ete and cte dimensions are only specified for

1. Gate valves PN10 to PN16
2. Ball valves PN10 to PN400
3. Globe and Lift Check Valves PN10 to PN40, Class 150, Class 300
4. Globe control valves PN10 to PN40, Class 150, Class 300

EN16722 will be referred to in future revisions of BS EN product standards. Manufacturer’s claiming compliance to a product standard will be required to comply with the end-toend and centre-to-end dimensions if they make any valves with pressure designations as detailed in 1. to 4. above.

Supersedes: New standard. Nothing to supersede
