Hydronic valves, manifolds, mixing valves, balancing valves and zone controls — the components that make a hydronic system controllable, balanced and safe. AHHAC supplies the Italian Barberi Rubinetterie Industriali range.
Every hydronic system lives or dies on its valves and controls. Get them right and the system balances itself, runs quietly and lasts decades; get them wrong and you'll chase noise, uneven rooms and short-cycling for years. AHHAC supplies and installs a complete hydronic valve and control package on every system.
Our preferred valve supplier is Barberi Rubinetterie Industriali — Italian-made since 1954, one of Europe's most respected hydronic component manufacturers. The Barberi catalogue covers manifolds, thermostatic mixing valves, zone valves, balancing valves, pressure-reducing valves, safety groups and the full range of hydronic brassware.
Distribution manifolds with individual loop control and flow meters. Thermostatic mixing valves to protect underfloor systems from boiler-temperature water. Motorised zone valves for per-zone on/off. Balancing valves to equalise flow across loops. Safety groups (pressure relief + gauge + air vent). Differential bypass valves to protect pumps. AHHAC sizes and specs every component to the system's flow and head.
"AHHAC delivered our 22-zone underfloor system on time, on budget and to spec. The crew were tidy, the documentation was thorough, and the commissioning was textbook."
"We've worked with AHHAC for 17 years. They've installed and serviced our hot water plant across three commercial buildings — and they pick up the phone on weekends."
"Three mobs quoted us; AHHAC's design was the only one based on a proper heat-loss calculation. The system runs beautifully — the others would've been oversized and expensive."
