IMI Hydronic Engineering product offering
Product offeringCore offering
IMI Hydronic Engineering (operating in North America as IMI Flow Design) manufactures and sells hydronic balancing and control valves for HVAC systems, including AutoFlow automatic balancing valves, Accusetter Venturi-based manual balancing valves, the Harmony pressure independent balancing and control valve (PIBCV), lead-free balancing valves (ICSS, UA Zero), VersaFlow hose kits, and supporting hook-up components. The product line covers sizes from 1/2 inch to 30 inches with threaded, grooved, flanged, and welded end connections for commercial hydronic applications.
Product overview
IMI Hydronic Engineering (branding as IMI Flow Design in North America) offers a comprehensive portfolio of hydronic balancing and control products for HVAC systems. The product line centers on two main balancing technologies: AutoFlow Automatic Balancing Valves (including AC/ACR, WS, WG, WB, WR, WT, YR, ACA/ACRA series) and Accusetter Manual Balancing Valves (including UA, UASBS, AF/AG, ET, VG/VF series). Supporting these core products are hook-up components (UB ball valves, YC/YCR strainers, BF butterfly valves), VersaFlow hose kits (Kit A, AC, B, C), and the Harmony Pressure Independent Balancing and Control Valve. The portfolio also includes lead-free options (ICSS, UA Zero) for potable water applications meeting NSF/ANSI 61-G and RLDWA 2014 standards. Products range from 1/2" to 30" in size with various connection types including threaded, grooved, flanged, and welded ends.
