Aquavault receives WRAS Approval

T-T Flow has been awarded renewal of accreditation from the Water Regulations Advisory Scheme Ltd (WRAS) for their range of Aquavault valves. The Aquavault, resilient seat wedge gate valve is used for pipeline isolation, and is suitable for potable water duties and buried service.

WRAS contributes to the protection of public health by preventing contamination of public water supplied by pumping wastewater away. They also encourage the efficient use of water by promoting and facilitating compliance with the Water Supply Regulations and Scottish Byelaws.

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 Aquavault, resilient seat wedge gate valves (DN50-DN300) has undergone rigorous testing procedures to gain the approval.

The now fully WRAS approved Aquavault Valves offer unique and lightweight epoxy coated ductile iron bodies, EPDM rubber coated ductile iron wedges and non-rising spindles with hand wheel or cap operating members. Features also include integral captive wedge nut for optimal lifespan, wax filled fasteners for corrosion resistance and stem seals that are replaceable under pressure. They offer a maximum working pressure of 16Bar and are suitable to work in temperatures ranging from -10 ºC to 70ºC.
