THEIR SIGNIFICANCE IN HEALTHCARE SETTINGS… Safeguarding healthcare environments with TMVs and the TMV3 standard
Mark Mogey, Head of OEM & ROI Sales at Altecnic.
Thermostatic Mixing Valves (TMVs) play a crucial role in maintaining water temperatures for various applications, ensuring safety and comfort. This is especially true in a healthcare environment, where the installation of TMVs allows for maintaining precise control over water temperatures, ensuring the safety of vulnerable patients, healthcare professionals and individuals within healthcare facilities. WHAT IS A THERMOSTATIC MIXING VALVE (TMV)? A TMV blends cold and hot water together and maintains this at a set constant outlet temperature to ensure safe and comfortable hand washing, shower and bath water temperatures, reducing the risk of scalding. HOW DOES A TMV WORK? The controlling element of the TMV is a temperature sensor which is fully immersed in the mixed water outlet port. This expands or contracts to continually maintain the correct proportion of hot and cold water entering the valve.

TMV3 provides assurance a TMV is tested and deemed safe to use in an NHS setting.
WHERE SHOULD TMVS BE INSTALLED? These valves should be installed in areas where people would be at risk of scalding. Different TMVs are available depending on the specification and standards that they meet and the type of property in which they are installed. These vary from healthcare and nursing home applications to installations from point of use of baths to centralised mixing in commercial properties such as sports facilities, where stable temperatures with high volume flow rates are required. When selecting and installing TMVs for healthcare environments, it is important to choose valves that adhere to TMV3 approval.
regulatory framework that has been established in the UK and ROI to ensure the safety and performance of thermostatic mixing valves used in healthcare and social care facilities in the UK. The TMV3 approval scheme provides assurance that a TMV is tested and deemed safe to use in an NHS setting. This scheme applies to TMVs for use in high-risk commercial healthcare applications within the UK. These valves offer a high level of protection, reacting much more quickly in shutting off the flow of water if the cold water fails, or a safe temperature is exceeded. Testing bodies must ensure that the valve adheres to the NHS D08 regulatory standard, which ensures stable temperature output despite varying supply pressures and temperatures.
