Motor valve and its application in heating and cooling systems

Motor valve and its application in heating and cooling systems

The motorized valve is a type of electric valve that is generally of the three-way valve type and is widely used in the HVAC (heating and cooling) industries.
The motorized valve is actually an electric actuator, it works with electricity and is responsible for controlling the flow rate and fluid throughput in air conditioning systems and central heating systems.

One of the most important applications of motorized valves is to use them in double boiler heating packages. As you know, dual wall or ground packages are responsible for heating the environment (radiators) and providing hot water for consumption. When the hot water tap is opened and the consumer is waiting for the touch of hot water, the motorized valve directs the hot water from the secondary heat exchanger built into the package.

Also, among other important applications of three-way motorized valves, we can mention their use in the water inlet path to the cold water coil or the hot water coil of air conditioners. When the air temperature of the indoor environment of the building reaches the desired temperature in the summer, the motor valve is commanded through the thermostat to send less cold water to the cold water coil of the air conditioner, and in the same way for the hot water entering the air conditioner coil in the winter.
Motorized three-way valves are also used in air conditioning and cooling devices such as fan coils and air conditioners.

Types of motor valves based on the type of movement

Motorized three-way valves are divided into two general types based on the type of movement in the system:

• Motorized valve with linear movement
• Rotary valve motor
• Of course, it is clear that this is not the only classification of these widely used products, but they can also be classified based on the type of function.

Mixer motor valve

This type of valve is used to connect and meet fluids of two different paths in a single heating or refrigeration system.

Divider motor valve

This type of three-way valve is used to divide the fluid flow into other flows.

Motorized valve to change the direction of fluid

As the name of this three-way motorized valve suggests, it is used to change the direction of the fluid in the piping system.
Motor valves or three-way valves have three branches and openings; One of these branches is the main way and the other two branches are secondary openings that make these products more flexible. This is the reason that these valves can be used to merge, divide and change fluid paths, and this is also the reason why motorized valves are widely used in the cooling and heating industry.

Components of motor valve

1. Engine
2. Three-way body
3. valve

The motor of motorized valves has three electrical connections, the combination of connections 1 and 2 and their downward movement opens the hot water bath, and the combination of connections 2 and 3 and their upward movement opens the path of the heating circuit in the package. It is heated.
It is worth mentioning that the packages that work with one converter and are called single converter packages do not have a three-way motor valve.
In general, motorized valves can be considered as a means to control and regulate the fluid flow rate, which fluid can be water, oil, air, and steam.
It should be noted that these products can even be used to control the flow rate of fluids such as gas and diesel, and by using them, leakage and foreseeable damages in the transmission system of these types of fluids can be prevented.
Motorized valves have low energy consumption and their presence can ensure the security of the system and increase its reliability.
