Reliance Heatguard Dual TMV2/3 Thermostatic Mixing Valve
Reliable Hot Water Temperature Control with TMV2 & TMV3 Protection
Controlling hot water temperature is essential for both comfort and safety. The Reliance Heatguard Dual TMV2/3 Thermostatic Mixing Valve blends hot and cold water to deliver a safe, stable outlet temperature, helping reduce the risk of scalding while maintaining reliable system performance.
Designed for both domestic and commercial applications, this high-performance thermostatic mixing valve complies with TMV2 and TMV3 standards, making it suitable for homes, healthcare environments, schools, care homes and other buildings where safe hot water delivery is essential.
The valve continuously monitors the incoming hot and cold water supplies. If either supply changes unexpectedly, the internal thermostatic element automatically adjusts the water mix to maintain the selected outlet temperature. Should the cold water supply fail completely, the valve rapidly shuts down the hot water flow, providing an important safety feature that helps prevent scalding.
Manufactured by Reliance Valves, a trusted name in plumbing and heating products, the Heatguard Dual combines precision engineering with durable construction to provide dependable long-term performance. Its compact design also makes installation straightforward while allowing easy access for servicing and routine maintenance.
