The temperature of the supplied hot water must be at least 5K above the desired blended water temperature for the JRGUMAT thermostatic mixing valve to function properly. Balanced hydraulic conditions at the hot and cold water inlet are crucial.

Excessively hot water can scald the skin. The maximum hot water temperatures at tapping points such as faucets or shower heads should therefore be limited. Because skin damage occurs within minutes at a water temperature of between just 45 and 51°C, within seconds at 51°C and above, and within a split second at over 70°C. In buildings with sensitive uses such as hospitals, care homes, schools and nurseries, but also within in hotels or apartments, the hot water can be set to a safe maximum temperature with the JRGUMAT thermostatic mixing valve.

On farms, for example, the JRGUMAT thermostatic mixing valve regulates the water temperature of drinking troughs for livestock or during feed preparation.

Hot water tempering valves are extremely detrimental and play an important role in any hot water system within your home, being a major part of protecting family members such as the young and elderly.

With the JRGUMAT thermostatic mixing valve from GF Piping Systems, mixed water with a constant temperature can be ensured in an energy-efficient manner - wherever this is desired or required. It is used in different system sizes and applications. The JRGUMAT thermostatic mixing valve is extremely durable and has proven its worth for decades.

The housing of the JRGUMAT thermostatic mixing valve is made of low-lead gunmetal. This alloy complies with the current EU lead limits and may be installed without hesitation until 2036 and used afterwards.

Your tempering valve is like any other fixture – over time they will deteriorate. Tempering valves should be replaced every 5 years to avoid failure. When a tempering valve fails, it will increase the risk of family members getting burnt. As water temperature increases, the contact time required to receive a third-degree burn decrease:

The installation instructions must be followed to ensure trouble-free function of the JRGUMAT thermostatic mixing valves. The local standards and guidelines must be observed

The JRGUMAT thermostatic mixing valve is an open architecture, proportionally regulating three-way mixer made of gunmetal. The blended water temperature is transferred to the thermostat. This compares the temperature with the set point. If the blended water temperature does not match the set point, the volume in the thermostat changes. This causes the valve slide to move across the pin so that more cold or hot water can flow in as required, until the blended water temperature matches the set point.

When water is heated using solar energy, pellet stoves or log heaters for example, high temperatures can occur in the hot water tank. The JRGUMAT thermostatic mixing valve regulates the hot water to the desired temperature.

When it comes to your hot water, it is important to ensure you consider the dangers that can occur, especially when it comes to the safety of children and elderly members of your family. It only takes half of a second for 70°C hot water to give a child third-degree burns. Installing a tempering valve will mix cold water into your hot water to prevent the water from getting too hot and burning any vulnerable family members. It has become an Australian regulation to have your hot water outlets fitted with a tempering valve that prevents water reaching above 50°C.

The thermostatic mixing valve works without outside energy. When integrated into a circulation system, the amount of hot water needed to cover heat losses is fed back into the storage tank or hot water generator. The rest is fed directly into the mixer.

JRGUMAT 3400 thermostatic mixing valves are currently available with factory-set standard temperatures (25/40/48/55°C). The individual settings range from a minimum of 20°C to a maximum of 65°C. Other types covering additional temperature ranges are available. It is possible to change the blended water temperature setting within the specified setting ranges of the respective thermostatic mixing valve.

We love what we do. Keeping your lights on, showers hot, toilets flushing and air conditioning running is what drives us every day. Our approach is simple, we do things the right way, not the easy way.

It is important to be aware of any signs of faulty or failing temperature valves, as it can be extremely dangerous if your valve begins to fail.

For advice, please contact your local technical customer services team or representative. We will be happy to advise you on the correct application and installation specifications.

If your hot water is 5 years or older, book a hot water inspection by one of our dedicated Hot Water System experts, at the all-inclusive price of only $258.00.

It is important to have your hot water system serviced every 5 years to ensure all valves are working correctly and ensure the safety of your family.

Thanks to their high control accuracy, JRGUMAT thermostatic mixing valves can be used for special applications, as regulating elements for maintaining temperatures or for processes requiring a constant water temperature. Wherever hands are not free to individually adjust the water temperature via a mixer tap, blended water set to the desired temperature comes in handy.

The JRGUMAT thermostatic mixing valve is also used as a thermal switch, for example in heat exchangers and hygiene storage tanks with different water temperature ranges.
