Valves - Isolating Regulating Valves - Variable Orfice, Double Regulating » NEXUS VALVE - Vertex Variable Orifice Double Regulating Valve (VODRV) with Drain

Nexus Valve Vertex is a variable orifice double regulating valve for balancing water-based heating and cooling systems. 

The balancing performed ensures the required distribution of flow in individual risers and terminal units. 

Applications are typically central heating or cooling systems, as well as fan coil units in multi-storey and high-rise buildings.

Nexus Valve Vertex is available in valves DN 10 to DN 50, manufactured in dezincification resistant brass (DZR). 

For valve sizes DN 65 - 600 the Nexus Valve Fluctus valve range is recommended.

Nexus Valve Vertex can optionally be provided with a drain valve. 

Apart from system draining, the drain valve can also be used to connect a capillary tube from the Nexus Valve Passim differential pressure control valve. 

The Nexus Valve Passim and Nexus Valve Vertex valves are in combination used for differential pressure control and maximum flow limiting.

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.
