Valves - Isolating Regulating Valves - Fixed Orfice, Double Regulating » NEXUS VALVE - Fluctus Fixed Orifice Double Regulating Valve (FODRV) without Drain

The Nexus Valve Fluctus is a range of manual balancing valves used in water-based heating and cooling systems to ensure an evenly distributed flow in zones, branches, risers and terminal units. Applications are typically central heating or cooling systems as well as fan coil units in multi-storey buildings.

The Nexus Valve Fluctus valve is compact having flow measuring, regulation and isolation functions all in one unit. The DN 15-50 valves are manufactured in denzincfication resistant brass (DR).

The Nexus Valve Fluctus has a built-in Venturi nozzle for accurate measuring. This design provides the Nexus Valve Fluctus with consistent measuring accuracy tolerances within ±3%, and the Nexus Valve Fluctus is more accurate than variable orifice double
regulating valves.

Because of the higher accuracy and low-pressure loss, the Nexus Valve Fluctus is more efficient for reduced energy consumption when heating and cooling systems are balanced.

Operating Conditions:
  • Temperature range: -20°C to 120°C
  • Max Pressure: 25 Bar

The Flamco Flexcon Calculation tool enables you to size and configure your pressurisation unit and all accessories you need for safe and problem free pressurisation of heating systems, cooling systems, water heating installations or pressure boosting sets.
