In drinking water supply and distribution installations, every component must guarantee the highest safety and reliability. At Comeval we are committed to technical excellence and regulatory compliance, which is why much of our hydraulic range carries the WRAS certificate, an international approval that vouches for the quality of products in contact with water intended for human consumption.

The WRAS (Water Regulations Advisory Scheme) certificate verifies that the materials used in the valves do not contaminate or alter the characteristics of drinking water. This recognition is obtained after passing technical, chemical and resistance tests carried out by accredited laboratories. Thanks to this process, the valves are confirmed not to affect public health or interfere with the quality standards required by current regulations.

Our WRAS certified water valves

At Comeval our UNIWAT^® range, designed for hydraulic systems and drinking water networks, includes WRAS certified valves. Among them are models such as gate valves, butterfly valves and check valves.

Benefits of the WRAS certificate for hydraulic projects

Using WRAS certified valves brings essential advantages such as health safety, international regulatory compliance, durability under real conditions and reduced technical or legal risk in critical installations. This certificate also becomes a differentiator against non-approved solutions, especially in public, industrial or water treatment projects.
