ESBE VRG133 Rotary Mixing Valve

The ESBE VRG133 rotary mixing valve is a compact 3‑way mixing valve with compression connections, designed for hydronic heating and cooling circuits. It is particularly suited to domestic boiler systems, distribution manifolds and underfloor heating loops. ESBE valves in the VRG133 collection are engineered to improve comfort by stabilising supply temperatures, enhance safety through reliable valve design and predictable control characteristics, and support energy efficiency when Kvs values are correctly matched to circuit flow for good valve authority. The VRG133 range offers DN20–DN25 sizes with several Kvs options to suit different branch and manifold capacities.
