Xterminator Overview

Marflow’s versatile Xterminator range of valve assemblies for fan coils, chilled beams and other hydronic terminal units offers significant benefits over standard products - for specifiers, installers, commissioning engineers and building operators/ owners.

The Xterminator valve assembly is a modular approach to meeting the flushing, flow balancing, isolation, and temperature control requirements of individual terminal units.

All Marflow products are supported by design and commissioning procedures that enables us to offer a wide range of solutions, reinforced by leading-edge design, installation and commissioning processes.

Involving Marflow at the concept stage of the project enables us to help with:

  • Selection of the most appropriate solution to meet design criteria
  • Accommodation of design changes and fine tuning
  • Provision of a comprehensive build schedule for manufacture
  • Provision of a complete site package for use during system installation and commissioning
  • Accommodation of future changes in system requirements

Marflow’s pre-fabricated valve assemblies ensure that everything required for a successful connection is supplied in one package. Furthermore, off-site assembly and testing reduces site time and virtually eliminates costly failures.

Xterminator units are available in Manual/Automatic/Pressure Independent Characterised Control Valves, offering different levels of functionality to meet the needs and budgets of each project, whilst sharing the high quality that is synonymous with the Marflow name.

Designers & Specifiers

  • Valve sizing undertaken by Marflow
  • Fewer components for each project
  • Flexibility in the type of pipe specified
  • Reduced CAD time
  • Choice of valve location, close coupled with terminal unit, or mounted in pipework
  • Packaged valve sets up to 2” diameter

Installers

  • Everything required for a successful connection assembly to a terminal unit is supplied in one package
  • Fewer components to be ordered for each project
  • Each Xterminator unit can be tagged and individually identified to each terminal unit
  • The Xterminator unit may be orientated in the horizontal or vertical plane on site
  • Two Xterminator units can be bracketed together with the Tandem Bracket
  • Euroconus connections allow various pipe types and diameters to be used for the runs connecting terminal units

Commissioning & Maintenance

  • The Filterball strainer is easily accessed without drain down
  • All valves required for commissioning of the terminal unit are in one location
  • Insulation boxes (when used) can be opened and re-sealed in seconds with no damage to pipe lagging
  • Automatic balancing valves reduce commissioning time to flushing and verification
  • Pressure independent valves offer full authority temperature control and maximum flow rate limiting
