Home » WRAS approved non-return valves: the highest safety standards for drinking water
The whole range of our Idrja and Small non-return valves has obtained WRAS (Water Regulations Advisory Scheme) certification, required in the United Kingdom for all materials and components used to transport drinking water. This certification defines the criteria and test methods applicable to material and products that come into contact with drinking water so as to ensure that they do not modify the characteristics (smell, taste, colour) of the water and that they do not release substances or allow bacteria to spread.
Manufactured items used in drinking water distribution systems, for example hydraulic valves installed in systems that distribute water that is also for human consumption, have to satisfy some particularly exacting requirements, and that’s how it should be because people’s health comes into play.
As the standard on which WRAS certification is based calls for items to pass very rigorous tests, it can be considered as a guarantee of safety and quality globally, and not just as an opening for product diffusion in the British market.
We wanted all our Idrja and Small non-return valves, made of AISI 304 or 316 stainless steel, to be certified. Even though initially for the intermediate range, certification was recently extended also to the smaller and larger valves. In this manner we can supply our clients with WRAS approved non-return valves to be used in the most varied applications, from machinery that requires the use of small valves, for example bottling machines, to systems for transporting large quantities of water.
We believe that certification from an accredited body that operates within a recognised system is an important confirmation of quality for the end user. It guarantees that the manufacturer has complied with all the sector reference regulations and that the product has all the characteristics required for its intended use. At the same time, certification stimulates the producer to continually update and monitor its work so as to improve constantly and retain certification.
The Idrja and Small check valves, in addition to having WRAS approval, are also NSF/ANSI 61 certified.
