Heatguard LS2 Thermostatic Mixing Valves - TMV2

TMV2 and WRAS Approved Thermostatic Mixing Valves

Reliance Water Controls Heatguard LS2 is a thermostatic mixing valve which is ideal for retrofit applications due to the L shape of the valve.

This design means that the hot water port and mixed outlet ports are opposite from each other reducing the need for pipework modifications.

The compact shape of the Heatguard LS2 allows for the TMV to be hidden behind a pedestal basin.

The LS2 thermostatic mixing valve is TMV2 approved for use within domestic and commercial or general public applications and is also WRAS approved and complies with BS EN 1111 regulations.

The Heatguard LS2 TMV provides stable mixed water temperature control and has a rapid failsafe on either hot or cold water supply in the event of supply failure.
