BELIMO R2050-40-S3+NR230A

The Belimo R2050‑S3 + NR230A is a ready-to-install valve-actuator set that simplifies fluid control in HVAC, hydronic heating, chilled‑water loops, and building water distribution systems. The DN50 ball valve offers high flow capacity (kvs 49 m³/h), making it ideal for main pipelines, risers, or large hydronic circuits where volume flow must be maintained. When paired with the 230 V rotary actuator, the system delivers smooth and reliable open/close operation under electric control — eliminating manual valve handling and enabling integration with Building Management Systems (BMS) or automated control panels.

This valve assembly supports water or water-glycol mixtures (up to 50 %) with fluid temperature ranging from –10 °C to +120 °C, accommodating a wide range of heating and cooling setups. Its high pressure tolerance (close‑off up to 1400 kPa) ensures stability and safety even under demanding system pressures. Because of its bubble‑tight seal when closed, the risk of leakage or water loss is minimized — a common problem with low-quality valves. The nickel-plated brass body and stainless steel internals provide corrosion resistance and long-term durability, while the actuator’s protective enclosure maintains performance in mechanical rooms or humid environments. Compared to assembling a separate valve and actuator manually — or using substandard valves — R2050‑S3 + NR230A offers a professional, factory‑matched solution that reduces installation time, ensures compatibility, and delivers dependable long-term performance for contractors, HVAC installers, and building managers.
