INDUSTRIAL VALVES — STEEL AND CAST IRON CHECK VALVES – NEW STANDARD ISSUED – BS EN 16767:2016

What is it?
This European Standard specifies the requirements for cast iron or steel check valves, which are forged, cast or fabricated in straight, angle or oblique pattern with end connections flanged or wafer, butt welding, socket welding, or threaded.

Previously the requirements for Cast Iron and for Steel Check Valves were specified in two separate documents BS EN 12334 and BS EN 14341 respectively.

Why is it important?
The main changes to the previous version of EN 12334:2001 and EN 14341:2006 are the following:

• Combined content from previous version of EN 12334:2001 and EN 14341:2006;

• Materials referenced to EN 12516-1 and/or to EN 12516-4;

• From EN 12334:2001, removal of informative Annex B “Comparison between EN and ISO cast iron material grades”;

• Revision of the normative references;
