Introducing the Thera-6 and V2000SX range

A one-fits-all solution for stockists, specifiers and installers, our new thermostatic valves and heads are designed to transform the performance, efficiency and reliability of home heating systems.

45 years of expertise

Built in Europe by a company with over 45 years of manufacturing expertise, our new range promises unrivalled style and engineering. We’re so confident of the quality of our products, we’ve guaranteed them for life.*

But premium quality doesn’t have to come at a price - the range is excellent value for wholesalers, specifiers and customers alike.

Stocking and specification are simpler too, with the new range supporting:

  • a wider number of applications – e.g. V2000SX meets 90% of all installation requirements
  • significantly fewer SKUs to stock, select and supply

Thera-6 thermostatic radiator valve head

Good looks that last

The Thera-6 universal-use thermostatic radiator head is amazingly compact and beautifully designed.

  • Rigorously engineered and tested for durability, making it ideal for residential heating applications
  • High control accuracy rating, supporting the highest energy efficiency standards of the new EN 215
  • Premium quality materials, with a lifetime guarantee on the radiator head.*

KEY FEATURES

  • Modern, minimalist compact design
  • Premium German-made sensor
  • Durable design with non-yellowing plastic shell
  • Best energy efficiency rating (to revised EN 215)
  • High-stroke variant for augmented flows or narrow p-band design
  • Range locking
  • Closed handle to prevent dust accumulation

The compact, energy-efficient Thera-6 thermostatic radiator heads are self-actuating controllers, regulating the flow of hot water through thermostatic radiator valves to continuously control the room temperature to the set-point selected on the head.

Installation

The V2036ESX valve can be used in multiple installations, rotating the valve to allow the Thera-6 head to point in the plane of the radiator or perpendicular to the radiator.

Ranges

Compact thermostatic head with closed design and high energy efficiency

V2000SX standard thermostatic valve

Fit for all occasions

One high quality valve for 90% of applications

The V2000SX thermostatic radiator valve range fits at least 90% of radiator applications, making it ideal for every installation, from new builds to retrofit projects.

  • Includes a variety of flow rate presets, covering a host of patterns and connection types
  • Tested beyond the requirements of applicable European quality standards with a strong spring and Resideo’s proven double o-ring sealing design
  • Designed with durability in mind, the V2000SX range is guaranteed for life*

KEY FEATURES

  • Bi-directional flow
  • 20 – 170 kg/h nominal flow with standard head
  • 20 – 210 kg/h nominal flow with high stroke head
  • Proportional flow control
  • Easy pre-setting to one of 6 setting values
  • 36 different patterns, sizes and connections
  • Standard M30 × 1.5 head connection

This range of pre-settable thermostatic radiator valves with a standard flow range is designed to balance almost all pumped two-pipe heating and cooling systems. It is recommended to fit them at the supply of a radiator, but fitting the valves at the return of the radiator is also possible.

Installation

The V2036ESX valve can be used in multiple installations, rotating the valve to allow the Thera-6 head to point in the plane of the radiator or perpendicular to the radiator.
