How do Thermostatic Mixing Valves Operate?

10 January 2022

Property owners these days maximise plumbing devices that can generate and distribute hot water to the sinks, showers, and other places. Hot water, after all, can provide a lot of benefits to people.

When utilised for taking a bath, hot water can easily relax and soothe one’s mind and body. Using hot water in cleaning the dishes or doing the laundry can then make the cleaning and disinfecting activities much easier as it can kill harmful germs, bacteria, and viruses. Hot water can also remove grime and stains that may be found on clothes, dirty dishes, utensils, and other kitchenware.

One essential plumbing device that can easily provide these benefits is the thermostatic mixing valve. A thermostatic mixing valve is a device that can effectively provide the needed hot water spontaneously without causing scalding or other hot-water related issues.

Primary Benefits of Thermostatic Mixing Valves

Having thermostatic mixing valves on your property can provide you with a lot of benefits. Some of the most notable benefits of these devices are as follows.

  • Prevent Scalding: One benefit of installing thermostatic mixing valves on your property is that they can prevent scalding and thermal shock. A lot of people who maximise taps without these thermostatic mixing valves tend to get scalded regularly. And once scalded, they would typically feel some pain and spot some burns on their skin. Using thermostatic mixing valves can prevent scalding as they can regulate water temperature effectively.
  • Mitigate Thermal Shock: Another benefit of installing and using thermostatic mixing valves is they can mitigate thermal shock. Thermal shocks often occur whenever the utilised water changes in temperatures abruptly. Alternatively, thermostatic mixing valves are effective in properties as they can maintain the temperature of the water all the time.
  • Preserve Property Value: One more benefit of maximising thermostatic mixing valves is that they can preserve the value of your property. Thermostatic mixing valves do not require the removal of the tiles just to make them operational, helping you preserve the appearance and value of your home. In just a few hours, you and others can safely take a bath or wash the dishes or clothes without costing and spending a lot of resources like time and money.

Thermostatic Mixing Valves Working Principles

A thermostatic mixing valve is primarily comprised of a hot water inlet port, cold water inlet port, mixed water outlet, thermostat element, slide valve, hot valve seat, and cold valve seat.

This specific plumbing device starts to operate whenever the thermostat element expands and contractors based on the changes of the temperature and relative pressure of the water, which comes from both hot and cold water inlet ports. As the element moves, the slide valve also moves to allocate the right amount of cold and hot water that is meant to enter the valve.

If the device has a low cold water supply, the thermostat element will expand while the slide valve closes the hot water valve seat, ensuring that the hot water supply will not reach the mixed water outlet.
