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

Why are three-way valves used?
The three-way valve is used in central heating installations. It can even be used for steel boilers. The three-way thermostatic valve controls the flow of the heating medium between a given heat source and the peripheral installation. Allows full temperature regulation. It is also worth knowing that a three-way valve is also called a three-way valve , so it is necessary in all heating installations, regardless of the type of boiler you have.
Three-way valves are used in places where the heating medium must supply both the central heating system and the hot water flowing in the 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 domestic water, but also radiators. So you can supply heat to the underfloor heating. The applications of the mixing valve are really wide. Please note that it is suitable for radiators, but also for various types of stoves. It is resistant to corrosion and mechanical damage. It gives off heat perfectly.
How correctly should a three-way valve be set?
For the entire installation to function properly, the three-way mixing valve must be properly set. 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 should be set to maintain the full flow path with the control lever positioned. The valve itself has a characteristic structure. One of the most important elements is the pin.
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 water flow. The three-way valve is used wherever the heating medium simultaneously supplies the central heating installation and also supplies utility water. Therefore, it is essential in the heating system. The use of mixing valves is very important because 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 against 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 installation. This ensures a comfortable temperature throughout the entire heating circuit. Also noteworthy is a four-way switching valve , which allows you to change the direction of liquid flow, but the most common is a three-way valve. Of course, pay attention to the valve diameter, which is selected according to the flow coefficient value, so you should check whether the pressure difference across 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 thing worth mentioning is the three-way valve with an actuator . You can choose an electric actuator equipped with a solenoid valve. Its method of operation is very simple, namely it is placed inside the body. It then redirects the water to one of three ports. It mixes hot water from the supply with cold water from the boiler.
In this way, the life of the boiler is also increased and fuel consumption is reduced. A three-way valve with an actuator can be used to direct water flow in central heating installations as well as in the cooling system. So the application is really wide. Although such a controller ensures safety, its price is very favorable.
When is it worth choosing a three-way thermostatic valve?
You can also choose a three-way thermostatic valve , which is part of the hydraulic equipment. It is used to lower the temperature of the heating circuit. Thanks to its use, you can set the temperature according to your 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 radiator. They maintain a constant temperature in the room. They can work with any boiler. Remember that if you start to feel too cold, 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 Afriso AZV 642 DN15 3-way valve, Kvs=8, G3/4" . 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 activated from any thermostat or switch. It can be used in central heating water systems. It can be safely matched to a heat pump or air conditioning system. The manufacturer uses the highest quality materials, which increases durability and mechanical resistance. It is controlled by a SPST signal power supply is 230 V.
Also noteworthy is the three-way valve Danfoss HRB3 32/ kVs=16 PN10, GW 1 1/4" . It is very functional. 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 enables quick installation into pipes, which in turn translates into the entire installation process. Of course, we must also mention that it guarantees maximum efficiency of liquid flow at a really low operating pressure.
In addition , the ESBE VRG131, dn25, KVS 10.1" three-way valve will be the right choice. It ensures maximum comfort for residents. It is used not only to supply the medium, but also to exchange water. It guarantees energy savings in both heating and cooling systems.
