It controls the valve directly. The easiest disk is manual. Here the adjustment is made by turning the plastic cap with a threaded connection. The bottom is in contact with the end of the rod. Turn the bobbin by turning or loosening. For the best van buom dieu khien bang dien this is important now.
The presence of an electric or servo drive allows you to program the temperature mode with an orientation at the time of the day. Initially, the drive mechanism is not included in the three-way valve package. It is purchased separately based on the characteristics of a particular heating system. The use of the product can be in the heating system of any design.
Where three-way valves are used
There are valves of this type in different schemes. They are included in the floor heating circuit diagram to ensure uniform heating of all components and to prevent overheating of individual branches. In the case of a solid fuel boiler, condensate is often observed in the room. The installation of a three-way valve will help combat it.
The three-way system works effectively in the heating system when the DHW circuit must be connected and the heat flow must be separated. The use of a valve in the binding of radiators eliminates the need for a bypass. If you install it on the return line, you create conditions for a device with a short circuit.
The nuances of the choice of devices
The following recommendations are common when choosing a suitable three-way valve:
- Preferred reputable manufacturers. Often there are poor quality valves in the market from unknown companies.
- Copper or brass products have higher wear resistance.
- Manual operation is more reliable but less functional.
The most important point is the technical parameters of the system in which it is supposed to be installed. The characteristics are taken into account: pressure level, highest coolant temperature at the installation point of the device, permissible pressure drop, the volume of water that passes through the valve.
Only the valve with the correct capacity will work properly. To do this, you must compare the performance of your plumbing system with the coefficient of the appliance’s processing capacity. It is necessarily marked on every model. For rooms with limited space, such as a bathroom, it is not efficient to choose an expensive thermo-mixing valve. A device with automatic temperature control is required on large surfaces with warm floors. The criterion for selection must also be the conformity of the product.
The costs can be very different. It all depends on the manufacturer. In-country houses with a solid fuel boiler installed, the heating schedule is not very complex. A three-way valve with a simplified design is reasonably suitable here. It functions autonomously and has no thermal head, a sensor and even a rod. The thermostatic element that controls its operation is adjusted to a specific temperature and is located in the housing.
Manufacturers of three-way devices
There is a wide range of three-way valves on the market from renowned and well-known manufacturers. The model can be selected after the general parameters of the product have been determined. The first place in the sales ranking is taken by valves from the established company. This is a fairly well-known brand, so three-way products are reliable and durable.
