Heatguard BF2-2 Thermostatic Mixing Valves - TMV2

TMV2 and WRAS Approved Thermostatic Mixing Valves

Reliance Water Control’s Heatguard BF2-2 is a thermostatic mixing valve approved for domestic and commercial/general public usage under the TMV2 scheme and is ideal for temperature controlled hot water in bath fill applications due to its design providing high flow rates at low pressures.

TMV2 Thermostatic Mixing ValveWRAS Approved Thermostatic Mixing Valve

The Heatguard BF2-2 thermostatic mixing valves provides precise, stable temperature control and has a rapid failsafe on either hot or cold water supply in the event of supply failure.

The Heatguard BF2-2 complies with BS EN 1111 and BS EN 1287 regulations and is WRAS approved.

Heatguard BF2-2 Thermostatic Mixing Valve

The Heatguard BF2-2 thermostatic mixing valve comes with either 2-in-1 fittings which include single check valves fitted to its inlets to prevent cross flow and disc type stainless steel strainers in front of the check cartridges to protect them from being damaged by system contamination or 4-in-1 fittings which have inlet fittings integrating isolation, filtration and test ports for temperature and pressure.
