The objective of this project is to qualify the EZ valve range (1 ½”, 2”, 3”, 4” and 6”) against current PIV approval standards GIS LC8-4. Subject to positive completion of this project and successful completion of project IL 405, I-0126 and Engineering approval this will enable deployment of a fully approved solution for installing of PIV’s into the UK Gas Network, without the need to interrupt or bypass customer’s gas supplies.

Previously a gap analysis test was carried out by Rosen comparing the American Water Works Association specification that the valve is currently approved to (C509) against UK Specifications (GIS V7-1 and BS EN 13774). Following this analysis and project work undertaken to date, further quality assurance and acceptance testing has been proposed by Rosen and agreed with Engineering to develop a qualification route for the EZ valve.

 

There will be no requirement for any further external testing after the completion of this project as stated by Rosen who have recommended the proposed testing in agreement with Engineering.

 

The project objectives are-

 

Full UK Type and Production testing for all five EZ valves in the range, in accordance with current industry standard (GIS LC8-4)
 
Material identification and mechanical testing of two EZ valves to confirm the materials used in the valve body, bolts and coatings.
