Available in both AVK’s Series 555 & Series 158, flanged or PE Tailed, the AVK Donkin Polyurethane coating, or “PUR” for short. The full Donkin Asset Protection system is comprised of five main elements that deliver these benefits: –
A unique, factory applied, high performance Polyurethane coating, specially developed by the team at AVK Donkin to withstand the rigors and challenges of underground installation. Factory fitted PE tails. Stainless Steel Spindle. Stem Cap. And the AVK Valve Installation Tracker to log, locate and audit the valve installation. This logs GPS location and provides full auditing of installed works. Take a photo of the valve in-situ with the Installation Tracker App & you have a 20-year guarantee at the ‘click’ of a camera.
The PUR is fully type tested to European standard EN 10290 and complies with all the relevant parts of UK gas standard T/SP/CW/6-2. The PUR undergoes additional site-specific tests to validate and approve the robustness of the coating. The system in its entirety has been designed to ensure that valve installations are quicker, of consistent high quality, are fully traceable and auditable. The system also improves the asset life and integrity of the valve whilst negating the need for additional protection systems. Installing an AVK UK Donkin PUR coated, PE tailed valve eliminates bolting connecting flanges and wrapping, which provides up to 3 hours of time saved that could be used elsewhere.
The Series 555 PUR range covers the standard Cast Iron PN16 Flanged Valve, from DN80 – DN300, which are 7bar rated and GIS/V7 pt1.
The Cast Iron Valve with PE Tails 90mm to 315mm, is 2-4bar rated dependent whether PE80 or PE100, it’s also GIS/V7 pt1 – GIS/PL3. Finally, AVK have a PUR range of Cast Steel 555, flanged PN16, DN80 – DN300 which is 16bar rated, GIS/V7 pt1. All 555s are Kite Marked.
The AVK Series 555 Valves are double block & bleed, with the options of ASA150 flanges, or Viton Seals, and Steel Valves have a weld-end option. All PUR Valves have Stainless steel Spindles, NBR Seals & a Stem Cap as standard.
AVK also supply the Series 158 Bi-Directional Drilling Valve in PUR, that also has the Stainless Steel Spindle, and is PN16 Lugged, c/w studs & nuts. The Series 158’s slim design helps with manoeuvring & positioning on site. The Valve is reduced in weight, clear bore, maintenance free and available from DN80 – DN400. 7bar rated except the DN400 which is 2bar. Covered by GIS/V7pt1 & Kite Marked.
The time saved by negating the need for wrapping the Valve after fitting and waiting on inspection provides you with valuable time savings which helps to complete works sooner.
