New range of air valves for portable and filtered water applications

Aquaflow Valves (UK), a division of T-T, has launched the AQUABRAKE range of air valves for potable and filtered water applications to compliment their already popular wastewater air valve series.

Whereas conventional air valves consist of internal pivots or mechanisms that are prone to failure, the AQUABRAKE features a single non-metallic directly acting float. The precision-machined guided cylindrical float is formed from solid polypropylene that will not deform or fail should surge conditions occur.

Due to the unique design of the patented vent assembly the AQUABRAKE has a single lightweight and compact fusion bonded epoxy coated ductile iron body that negates the need for a secondary small orifice chamber, which reduces weight for ease of installation and minimises transportation costs.

The uncomplicated modular body allows the valve to transform from a 16 Bar rated configuration to a 25 or 40 Bar rating within seconds without the need for specialist tools or workshop facilities.

Available in two configurations either single large orifice allowing for efficient bulk release of air during pipe filling to prevent pressure build-ups and ingress during pipe draining to prevent vacuum conditions arising; and double orifice offering as the single orifice plus a controlled bleed facility to maintain system stability.

The innovative design ensures that the AQUABRAKE offers excellent flow performance even when operating under demanding conditions. Conforming to BS EN 1074-4:2000, tested to EN 12266-1:2003, available from DN25 through to DN200 and approved by the Water Regulations Advisory Scheme (WRAS). Having a proven pedigree with installations across Europe and as far away as Australia.

Accessories to enhance the AQUABRAKE include an integral engineered surge alleviation assembly, tapped cowl, insect mesh and isolating valves.

In addition, Aquaflow Valves can supply from its extensive stockholding a range of waterworks valves including; engineered wedge gate valve valves (manual or actuated), WRAS approved swing check valves, double hinge flap valves and fabricated valve operating equipment.
