Objectives The full range of EZ valves will be supplied and installed onto sample pipe by AVT. All 5 valve sizes within the EZ Valve range will be subjected to the appropriate approval/performance testing in accordance with gas industry standards (GIS V7-1). A further two EZ Valves will be subjected to material identification and mechanical testing. This project has been developed to enable a qualification route for the EZ Valve range as a fully deployable Cadent approved solution onto its network AVT: a. Supply of two complete valve sets (1 ½”, 2”, 3”, 4” and 6”) 10 in total including shipping. b. Supply of 1no old 4 inch nominal diameter grey iron pipe (pit cast grey iron or spun cast grey iron) minimum length 1.1 meters c. Installation of 10 Valves by AVT onto sample pipe at Rosen testing facility, unit 1 Brunswick Industrial estate, Newcastle upon Tyne, NE137BA. All tools and equipment will be provided by AVT to enable this. Installation will be observed by Rosen representatives. d. Supply material property specifications and equivalent BS EN standards (or nearest accepted equivalent) ROSEN: a. Material Identification testing 1. Manufacturer will provide material property specification and equivalent BS EN standards (or nearest accepted equivalent) 2. Cast metal material identification a. Valve body and any other cast component b. Confirmation of mechanical properties-tensile, toughness, charpy (strain test), Micro and Macro examination of materials. 3. Coating material identification 4. Bolt Material a. Identification of specification b. Confirmation of mechanical properties – tensile, toughness, charpy (strain test), Micro and Macro examination of materials. Material testing will be undertaken on one valve from each foundry.b. Full type testing as specified in GIS/V7-1 (Current UK gas industry valve standard) 1. Shell strength test 2. Obturator strength test 3. External leak test at temperature extremes 4. Internal leak test (let-by) at temperature extremes 5. Operability test 6. Bending test 7. Resistance to Liquid agents test 8. Wear test 9. Strength of stops 10. Resistance to bending movement applied via the spindle head. c. Production testing as specified in GIS V7-1 GIS V7-1 Production tests are required once type testing has been satisfactorily achieved and consists of the following tests; 1. Shell strength test 2. Obturator strength test 3. Internal leak tightness 4. Operability test 5. External leak tightness 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 Network policy 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 Network policy 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 V7-1) • Material identification and mechanical testing of two EZ valves to confirm the materials used in the valve body, bolts and coatings. 
Abstract 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 V7-1 (excluding the double block and bleed test as the EZ valve does not have this facility) Subject to positive completion of this project and successful completion of project IL 405 and policy approval this will enable deployment of a fully approved solution for installing of PIVs into the UK Gas Network, without the need to interrupt or bypass customers gas supplies.
