Properly selected valves affect the operation of the entire installation. Mixing valves are worth attention. It is worth learning more about what a three-way valve is. Today we will also present you with models worth choosing. You will also learn how to choose a mixing valve for a central heating installation.

Why are three-way valves used?
A three-way valve is used in central heating systems. It can even be used in steel boilers. A three-way thermostatic valve controls the flow of the heating medium between a given heat source and a peripheral system. It allows for full temperature regulation. It is also worth knowing that a three-way valve is also called a three-way valve , so it is essential in all heating systems, regardless of the boiler you have.
Three-way valves are used in places where the heating medium must supply both the central heating system and hot water flowing in taps. It can also be used where there are two heat sources, i.e. a gas furnace and a solid fuel boiler. In this case, the device will heat utility water, but also radiators. So, heat can be supplied to underfloor heating. The use of the mixing valve is really wide. Note that it will work well for radiators, but also various types of furnaces. It is resistant to corrosion and mechanical damage. It gives off heat perfectly.
How should a three-way valve be properly set?
In order for the entire installation to function properly, the three-way mixing valve must be set correctly. It should be set so that the water returning to the boiler has a temperature of at least 50-60 degrees. In fact, each 90-degree turn changes the operation of the entire valve. The three-way valve must be set so that the full flow path is maintained, and this is with the control lever in the position. The valve itself has a characteristic structure. One of the most important elements is the stem.
It also consists of an element such as a body, which can be made of brass or stainless steel, and also consists of a valve that ensures the flow of water. A three-way valve is used wherever the heating medium simultaneously supplies the central heating system, but also supplies utility water. It is therefore essential in a heating system. The use of mixing valves is very important, as it also affects safety. A thermostatic mixing valve controls the flow of heated water, the temperature of which can be very high, and prevents scalding. Additionally, it protects heating devices from overheating.
Which three-way valve for a heat pump?
Many users wonder which three-way valve to choose when they have a heat pump. You can choose a three-way model. The three-way valve in the heat pump mixes hot water from the boiler supply with cold water that returns from the system. This allows you to achieve a comfortable temperature in the entire heating circuit. The four-way switching valve , which allows you to change the direction of the liquid flow, is also worth noting, but a three-way valve is most often used. Of course, pay attention to the valve diameter, which is selected for the flow coefficient value, so you should check whether the pressure difference on the valve does not exceed the available one. When heating your house with a heat pump, you should use a three-way valve, which is essential.
Principle of operation of a three-way valve with an actuator
Another noteworthy feature is the three-way valve with an actuator . You can choose an electric actuator that is equipped with a solenoid valve. Its method of operation is very simple, namely it is placed inside the body. Then it redirects the water to one of the three ports. It mixes hot water from the supply with cold water from the boiler.
This also increases the life of the boiler and reduces fuel consumption. A three-way valve with an actuator can be used to direct the flow of water in central heating systems, as well as in the cooling system. Therefore, the application is really wide. Such a controller, although it ensures safety, its price is very favorable.
When is it best to choose a three-way thermostatic valve?
You can also decide on a three-way thermostatic valve , which is an element of hydraulic equipment. It is used to lower the temperature of the heating circuit. Thanks to its use, the temperature can be set according to your own needs and very precisely. Of course, it should be selected in terms of diameter.
This will make mixing cold and hot water even more effective. Thermostatic valves are suitable for a radiator. They maintain a constant temperature in the room. They can work with any boiler. Remember that if you start to feel too cold, then the safety valve is open.
As a result, the water flow in the radiator will increase, which in turn will increase the temperature and the heating will be more comfortable. At the same time, there will be no heat loss. The thermostatic valve can also regulate the operation of the head. It is used for control.

It is worth choosing the 3- way Afriso AZV 642 DN15, Kvs=8, G3/4" 3-way valve . This Afriso three-way valve is really durable, resistant to mechanical damage. It is used as a switching element. It should be noted that it can be started from any thermostat or switch. It is used in central heating water installations. You can safely choose it for a heat pump or air conditioning system. The manufacturer used the highest quality materials, which increases durability and mechanical resistance. It is controlled by an SPST signal. Its supply voltage is 230 V.
The Danfoss HRB3 32/ kVs=16 PN10, GW 1 1/4" three-way valve is also worth mentioning. It is characterized by really high functionality. Thanks to the use of brass, it is resistant to corrosion and will serve for a really long time. Also pay attention to the internal thread, which allows for quick assembly to the pipes, which in turn translates into the entire installation process. Of course, we must also mention that it guarantees maximum fluid flow efficiency and this at a really low working pressure.
In addition, the ESBE VRG131, dn25, KVS 10, 1" three-way valve will be a suitable choice. It provides maximum comfort for residents. It is used not only for supplying the medium, but also for water exchange. It guarantees energy savings in both heating and cooling systems.
