3 outlets thermostat valves

Shower Valves Guide


The shower valve performs two crucial tasks: controlling the flow of water and regulating water temperature in the shower. Depending on their functionality, there are two main types of shower valves: manual mixer valves and the thermostatically controlled valve. The diverter feature is available on all shower valves – apart from the basic ones. Water can be allowed into the shower head by flicking the diverter switch. Shower valves with premium features will enable you to use the taps and the shower simultaneously. 

Shower valves can also be exposed or concealed. Unlike concealed shower valves, exposed shower valves have the entire hot and cold system and the pipes installed above the showerhead. Most homes and hotels nowadays have concealed shower valves. 

 Manual showers valves

A manually operated shower has its water flow entirely controlled by the user. They adjust the temperature of the spray by turning one or more handles until they feel comfortable with it. The way they are operated is similar to a basin tap, and most modern valves are controlled by a single lever that controls the temperature and water flow. As a result, manual showers are easily operated, but their user-controlled nature makes them susceptible to hot and cold bursts if someone flushes the toilet or runs the tap elsewhere in the house at the same time. Generally, units will work with either high or low-pressure water, but this can vary from model to model, which is why it's essential to check before buying.

Thermostatic showers valves

The thermostatic cartridge constantly monitors the water temperature to ensure that it is kept at the selected temperature in thermostatic showers. When the supply of hot or cold water changes, the thermostat adjusts the flow so that the user does not feel any difference; additionally, some thermostats automatically shut off when the water level is insufficient, preventing sudden water bursts at either end of the temperature range. You can control temperature and flow separately with two or three handles until you find the perfect shower. In this way, future showers will be perfect when they are turned on, saving you both time and money. They are an excellent choice for a family with small children.

 Due to its simplicity and ease of use, a manual shower valve is extremely popular. This valve only has one lever that can control both the flow of water and the temperature. Controlling the temperature and pressure of the water with a lever is moderately simple. The valve works well in most secondary bathrooms. Temperatures can be maintained at a comfortable level anywhere in the shower, thanks to a thermostatic valve. The main benefit of this valve is that it prevents the temperature of the water from exceeding a pre-set threshold. If you care about maintaining a child-friendly temperature, then this feature is essential.

Temperature-regulating shower valves (or TMV valves) ensure that the water temperature is consistently maintained. The shower valve prevents the water from turning cold or scalding hot if someone turns on a tap or flushes a toilet elsewhere in the house. The anti-scald device is automatically activated when this valve is installed, so you are always safe while showering.

A thermostatic shower valve typically has two or more handles - the first controls the flow, the second controls the temperature. As soon as you have reached the desired temperature, you can leave that handle in the same position so that each time you use the shower, you only need to turn it on/off.

Reasons to choose a thermostatic shower valve:

  • Precise thermostatic control ensures a constant temperature
  • Suitable for families with young children
  • Use with any shower outlet you want
  • Anti-scald technology

How does it work?

Temperature-sensitive elements are used in mixing valves to expand and contract based on modulating water supply temperatures. The water remains constant by keeping the slide valve at an adjustable amount of hot and cold water as the element contracts and expands.

In case of water shortage, the valve will automatically close off the hot water supply when the element expands and pushes the slide valve down, preventing scalding by cutting off the water supply.

 Decide what kind of shower system you want before choosing a shower valve. For example, What would be more suitable for your needs: a simple slide rail system with a hand shower or a more elaborate design with a fixed shower head, handset, and body jets? As soon as you make this decision, you can choose the shower valve type that will work best for you. Below is an explanation of the different types.

A thermostatic shower valve has two outlets - one is used for the shower head. The first handle controls the temperature, while the second handle controls water flow.

Triple thermostatic shower valve - outputs water to 2 outlets, including a body jet and a fixed shower head that can run simultaneously. Temperature is controlled by one handle, while two others control flow controls.

Dual thermostatic shower valve with diverter - supplies water to two outlets, such as a fixed shower head and handset. You can control the temperature with one handle and change between functions with the other.

Water can be supplied to 3 outlets with a triple thermostatic shower valve, including a fixed shower head, handset, and body jets. You can control the temperature on one handle and switch the water flow on the other, a diverter. Lastly, a flow control allows you to control an additional outlet, such as the body jets.
