Swing check valves gain WRAS Reg4 certification
T-T Flow’s full range of swing check valves has been awarded accreditation from the Water Regulations Advisory Scheme (WRAS).
WRAS is one of the bodies which contributes to the protection of public health by preventing contamination of public water supplies and encouraging the efficient use of water by promoting and facilitating compliance with the Water Supply Regulations and Scottish Byelaws. These require that a water fitting should not cause waste, misuse, undue consumption or contamination of the water supply, and must be ‘of an appropriate quality and standard’.
To qualify for WRAS Reg4 certification, which is recognised as evidence of compliance by every water supplier in the UK, the full range of swing check valves has undergone a rigorous testing procedure for certification.
The now fully WRAS Reg4 certified swing gate valves (DN50-DN300) offer epoxy-coated ductile iron bodies and metal-to-metal seals for vertical and horizontal installation. These models are available with an optional external weighted arm. This valve is used to prevent reverse flow and is suitable for potable water, wastewater, and sewage applications.
