Zone thermoregulation is one of the most virtuous practices in home energy efficiency. To achieve this, it is necessary to be able to control the thermodynamic fluid circulating in the system; motorized zone valves are the perfect tool to make this process automatic.

Zone valves are devices for shutting off and diverting the heat transfer fluid (usually water) used in heating, cooling, or plumbing systems. There are several types of zone valves that differ in the shape of the cone, the type of actuator, the number of ways, and the number of positions.

The plug is nothing more than the internal part of the valve. Its movement allows it to intercept and divert the heat transfer fluid. It is moved by the actuator - a mechanical device that can be operated manually or electrically. Parameters such as number of ways or number of positions allow the valve to be used according to different operating principles: For example, 2-way valves are used primarily for on/off or modulating service, while 3-way valves are also used as diverters or mixers.

A zone valve is said to be motorized when it is equipped with an actuator that can be operated by electric servomotors without any manual intervention. In this case, the movement of the shutter is controlled by an electric servomotor able to interpret the signals received from the thermostat thanks to the presence of a control unit.

Motorized zone valves allow you to control the temperature of your home by using the indications from the room sensors of the thermostats to divert, where necessary, the heat carried by the heat transfer fluid to the zone that needs it most.

Motorized valves should be connected individually to the various room thermostats, as many as there are zones to be controlled.

Zone valves are an optimal solution for those who want to manage the heating of the home on multiple levels, while keeping an eye on consumption and maximizing the energy efficiency of the system. In addition, zone valves are suitable for many situations in both residential and industrial environments, thanks in part to the variety of products and configurations available on the market.
