What AVK does

AVK UK designs, manufactures, and supplies valves, fittings, and hydrants for the UK's water, gas, wastewater, and fire protection sectors. The company operates as the UK arm of the privately held AVK Group (founded 1941 by Niels Aage Kjaer), running 7 UK companies with 500+ employees, UK headquarters in Northampton, manufacturing at Staveley (Chesterfield), and a Smart Water Academy in Kilmarnock. The core physical product range encompasses gate, butterfly, plug, and non-return valves; underground fire hydrants (Series 29/91, 29/288, 29/61); dismantling joints; and hydrant security devices, all carrying Kitemark BS750, WRAS, UKCA/CE, and WIMES compliance.

The company's strategic differentiator is the VIDI Smart Water platform: battery-operated wireless IoT sensors (positioner, pressure, flow, temperature, level, open/close) with up to 10-year battery life, transmitting via NB-IoT or LoRaWAN. The paired VIDI Cloud software offers tiered subscriptions (Basic, Advanced with alarm dispatching, Premium with DMA-based leak detection, plus a 6-month Pilot trial) and exposes a free API for SCADA, GIS, and BMS integration. The AVK Assist mobile app adds QR-based asset tracking, BIM-compatible augmented reality, and engineering calculators.

AVK makes money primarily through quote-based hardware sales of valves, fittings, hydrants, and VIDI sensors to UK utilities (water, wastewater, gas networks, fire services) and contractors, supplemented by recurring revenue from VIDI Cloud software subscriptions and VIDI Device Hub monthly fees for LoRa devices. Distribution combines a direct enterprise sales force (named account managers and project sales specialists) with a UK distributor network including Wolseley UK. Named reference customers include United Utilities, Yorkshire Water, Wessex Water, South West Water, Irish Water, Severn Trent, Anglian Water, Hafren Dyfrdwy, and Cork County Council, with major project involvement such as South West Water's Mayflower 90 MLD water treatment works (with actuator partners AUMA and Rotork).

Core offering

AVK UK designs, manufactures and supplies valves, fittings, underground hydrants, dismantling joints and ancillary products for water supply, wastewater, gas distribution and fire protection networks, selling directly to utilities and contractors and through UK distributors. Building on this hardware base, AVK sells the VIDI Smart Water platform — battery-operated wireless IoT sensors (positioner, pressure, flow, temperature, level, open/close) transmitting via NB-IoT or LoRaWAN to the VIDI Cloud software for remote network monitoring, alarm management and leakage detection. The company also offers the AVK Assist mobile app and the Autofrost Valve technology for hydrant frost protection.

Product overview

AVK is a provider of smart flow control, pressure management, valves and fittings for the water and gas utilities sector. The product portfolio centers on the AVK Smart Water platform — a digital monitoring solution combining battery-operated wireless VIDI sensors (VIDI Positioner, VIDI Pressure, VIDI Flow, VIDI Temperature, VIDI Level, VIDI Open/Close) with VIDI Cloud software for data visualization, alarm management, and leakage detection. Smart Water sensors transmit via NB-IoT or LoRaWAN to VIDI Cloud or third-party SCADA/GIS systems. Core physical products include underground fire hydrants (Series 29/91, 29/288, 29/61), gate valves, dismantling joints, and hydrant security devices. The AVK Assist mobile app (iOS/Android) provides QR-based asset tracking, augmented reality for BIM models, and technical calculation tools. All products support the water distribution network sectors of water supply, wastewater, gas networks, and fire protection.
