Whatever your system requires, we can fulfill your needs quickly and affordably. To learn more about nexus valve visit our website:

Automatic Flow Control Valves: The UltraMatic™ maintains your specified flow rate at ±5% to ensure occupant comfort and system balance with maximum efficiency. Add our exclusive NexPress™and NexLok™ connection system for a quick and clean install. Save time and money with a dynamically balanced and efficient system.

Manual Flow Control Valves: Choosing a circuit balancing valve is not rocket science; developing a good circuit balancing valve is. With Nexus’ modular valve design, end fitting choices and wide selection of Cv values, there is certain to be circuit balancing valve to fit your application.

Pressure Independent Control Valves: The Dynamic™ & VIvax™ PICV (Pressure Independent Control Valve) is a differential pressure regular, adjustable constant flow limiter, and high authority temperature control valve.Both valves are designed to deliver precision flow with high range ability to maximize the energy savings of variable volume and constant volume HVAC systems and components while providing increased environmental control and occupant comfort.

Coil Paks: Manual or Automatic? That should be your toughest choice when selecting a Nexus Valve Coil Pak. For years, contractors and manufacturers have been using individual components to make piping packages. With Nexus Valve’s Coil Paks, pre-configured and leak tested assemblies are available to reduce expensive field labor as well as eliminate potential leak points.

Avoid expensive, labor intensive pre-flush and post flush assembly or maintenance. Save valuable time and money with the UltraBK™ Bypass and Flushing Kits.

Air & Dirt Elimination:Air and dirt in a system causes problems such as reduced heat transfer, unnecessary faults, wear, noise and can lead to disruptions of the system and reduced pump performance. Higher energy consumption and an unreliable system are the consequence. The Commercial Flamcovent Clean Smart air and dirt separator removes the smallest microbubble and minuscule dirt particle from the system water. The innovative design leaves the pressure loss in the system to a negligible minimum.

Vacuum Dearator: The Flamco PSD is used to remove dissolved air from sealed chilled and heating water systems. The equipment utilizes a multi function digital controller with a simple user interface. The equipment is an advanced product that combines a pressure step principle with side system configuration to minimize the effects on the sealed system. The real-time display shows the status of the equipment while monitoring the system pressure and health of its own components.
