T-T Flow announced on 16 May that they have been awarded accreditation from the Water Regulations Advisory Scheme (WRAS) for all its swing gate valves.

WRAS 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’.

WRAS approval is granted directly by representatives of the water suppliers and is accepted as evidence of compliance by every water supplier in the UK.  To qualify, the full range of swing check valves has undergone testing for the approval. 

The now WRAS approved 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.

WRAS approved products can be identified through the WRAS logo displayed on product pages.
