NEXUS VALVE VERTEX VODRV / SERVICE VALVE
Static circuit control valve
The Nexus Valve Vertex VODRV (variable orifice double regulation valve) is a dual control valve with a variable opening designed for balancing heating and cooling systems.
Hydraulic balancing guarantees an even flow of water through the individual risers and loads.
Typical applications include central heating and cooling systems and fan-assisted heat exchanger systems in multiple-storey residential buildings and high-rise buildings.
Nexus Valve Vertex combines flow readings, pre-adjustment and shut-off function – all in a single unit.
This design also makes the Nexus Valve Vertex ideal for restricted spaces or awkward locations. The Nexus Valve Vertex is simple to pre-adjust using a hexagon socket wrench.
On completion of the pre-adjustment the settings remain fixed. The Nexus Valve Vertex pre-adjustment and shut-off functions work independently of one another.
The system flow can then be shut off without changing the pre-adjustments. The Nexus Valve Vertex comes with a drain valve as an optional extra.
The Nexus Valve Vertex with drainage device may be combined with the Nexus Valve Passim differential pressure control valve using a capillary tube. Using the Nexus Valve Vertex and the Nexus Valve Passim simultaneously in a system section with consumers, eliminates pressure fluctuations in the section in question.
The constant differential pressure regulation prevents the pre-adjusted design flow of the Nexus Valve Vertex from being exceeded.
