BELIMO R2040-S2+LR230A

The Belimo R2040‑S2+LR230A bundle delivers a complete, ready-to-use solution for water or glycol circulation control in HVAC, chilled-water, heating, or hydronic systems. The DN 40 ball valve ensures strong flow capacity (Kvs ~31 m³/h), making it suitable for large pipes — ideal for central cooling/heating loops, building risers, or boiler‑based hot water distribution. Paired with the 5 Nm 230 V AC actuator, this assembly automates valve opening and closing based on control signals, eliminating manual adjustment and enabling seamless integration with building management systems.

Because the valve is rated for fluid temperatures from –10 °C up to +120 °C and supports water or water-glycol mixtures (up to 50%), it caters to a broad range of installations — from chilled water air‑handling units to hot water radiator systems. The ball valve’s nickel‑plated brass body and stainless‑steel internals deliver durability and corrosion resistance, while the actuator’s IP54‑rated housing ensures reliable operation even in utility rooms or damp mechanical spaces. Compared to manual valves or mismatched valve‑actuator combinations, this Belimo unit offers consistent shut‑off, higher flow capacity, protected actuator, and a professionally integrated package — reducing leak risk, installation complexity, and maintenance needs over time. A smart choice for contractors, HVAC installers, or system integrators focused on reliability and performance.
