AVK UK Ltd products

The AVK automatic air valve is designed for water and neutral liquids with operating temperatures up to 60°C, capable of withstanding temporary peaks up to 90°C. This valve incorporates a sensitive seal for effective air discharge from pressurized systems, ensuring minimal obstruction from debris. With a 12mm orifice, the valve is engineered for high flow rates and enhanced operational efficiency. Constructed from corrosion-resistant materials, all components are selected to provide durability and longevity. The lightweight and compact design makes it easy to integrate into various water network systems.

The AVK Series 701/13 is a compact and effective single orifice automatic air relief valve, designed for use with potable and filtered raw water systems. Engineered with a grey cast iron body and a brass base, the valve supports a maximum working pressure of 16 bar and operates within a temperature range of -10°C to +70°C. It is essential to insulate the valve for temperatures at or below 0°C. The product meets rigorous standards and holds certifications such as WRAS valid until September 2024 and DVGW NW-6215BS5030 Aquestia. The model is particularly suitable for ensuring system efficiency by efficiently releasing trapped air within water pipelines, thus preventing potential issues related to airlocks and pressure build-ups.

The AVK metal seated wedge gate valve, compliant with BSEN1074-2/BS5163-1 standards, is designed to regulate the flow isolation in pipelines or equipment. It is suitable for drinking water and neutral liquids up to a maximum temperature of 70°C. Constructed with a ductile iron gate and bronze rings, the valve ensures a watertight seal. The non-rising stem design maintains lubrication of the stem thread through water passing within, enhancing valve longevity. This valve aims to provide a reliable sealing mechanism and efficiency in various water supply networks.

The AVK metal seated gate valve with ISO flange PN16 is designed for flow isolation in pipelines and equipment handling drinking water and neutral liquids with temperatures up to 70°C. The valve features a ductile iron gate with bronze rings that ensure a watertight seal. Its non-rising stem design ensures the stem thread remains lubricated by the passing water, enhancing the valve's longevity. The valve includes a bronze wedge nut for optimal compatibility with the stem and a machined face ring for a tight seal with the body seat ring. Other features include guides for uniform closure, a large bore to prevent stagnant water and impurities, an EPDM bonnet gasket, and countersunk stainless steel bonnet bolts. The internal and external surfaces are coated with blue two-pack epoxy, and the valve is suitable for both horizontal and vertical installations.

The AVK Series 29/26-001 is a resilient seated, isolating, clear way, sandwich gate valve that features PN16/PN25 flange drilling and a ductile iron body and bonnet. This valve is particularly suited for use as a hydrant isolator or for isolating applications under pressure drilling, offering benefits such as reduced drill stroke. The valve is designed for neutral liquids including water, with a temperature range of -10°C to 70°C. It includes a 1.4021 stem and galvanized bonnet bolts. Compliance with EN 1074-1 and EN 12266 standards for hydraulic testing ensures its reliability and performance in technical applications. The design aims to facilitate efficient maintenance procedures, thereby extending the lifespan and functionality of the valve.
