A Beginner’s Guide to the Belimo Valve Actuator in 2025

A belimo valve actuator is a device that uses an electric motor to control the flow of liquid or air into the HVAC system by regulating the opening and closing of the valve. The valves ensure precision, reliability, and efficiency of the HVAC system or fan coil unit. If you, too, are on the lookout for the best valve actuator, then the brand belimo stands out. They have the most advanced actuators in the year 2025, which redefine the functioning of the HVAC system. This guide is one that every beginner must go through to get the most out of the valve actuator. 

What is a Valve Actuator? 

A valve actuator’s role is to handle the opening and closing of the valve in the actuator system in mechanical machinery, like an HVAC setup. It regulates the flow of the heating and cooling fluid, like water and glycol. The regulation of the flow rate helps in maintaining a consistent temperature, as well as leading to energy conversion. 

• The valve manages the flow of the liquid and gas.

• The actuator part moves the valve based on the input signals from the building automation system (BAS). 

How Does the Belimo Valve Actuator Work?

The functioning of belimo is based on automation and control signals. Here are the brief steps to understand the working principle better.

• Single Input:

The actuator receives the signal from the building management system (BMS). The signal can be analog form, like 0–10V or 4–20mA, or even in a digital format like Modbus, BACnet, or MP-Bus.

• Actuation:

The actuator converts the electrical signal into mechanical motion, which adjusts the position of the valve. It can be either opening, closing, or just midway. 

• Feedback:

Some of the advanced models also send real-time performance and monitoring data to the BMS, which allows precise monitoring and optimization. 

• Flow Regulation:

The actuator continuously adjusts the valve position, sensing the temperature and pressure change. Thus, the flexibility in sensing the surrounding environment ensures a comfortable environment. 

The process is automated and continuous, which makes the brand belimo stand out. It helps in maintaining the indoor climate consistent, especially in large spaces like hospitals, malls, and server rooms. 

Types of Belimo Valve Actuator 

The brand belimo has its own range of actuators, with different specifications. You can choose the one according to your requirements.

• Rotary Actuators: 

It is mostly used in the buttery valve or the rotary valve, which provides rotational motion to open or close the valve. If you are looking for a compact and easy-to-use actuator, then this is the one. 

• Linear Actuators:

As the name suggests, these actuators move in a straight line, perfect for a globe valve that needs accuracy in modulation. It is apt for a machine that wants fine control flow. 

• Pressure-Independent Valve Actuators:

It consists of a control valve, a pressure regulator, and an actuator all in one unit. It helps in maintaining the constant flow without any pressure fluctuations. It ensures the stable performance of the HVAC system or any valve-based machine. 

• Characterized Control Valve Actuators: 

Also known as CCV actuators, it provides high accuracy for the heating and cooling coils. The ergonomic design of the valve is such that it allows equal percentage flow of both liquids, making the operations precise. It also reduces the need for energy, providing a perfect merge of efficiency and cost-saving. 

• Smart &  IoT-Enabled Actuators:

The electronics are becoming technologically advanced, which includes cloud connectivity & IoT integration. It also has real-time data monitoring, remote configuration, and maintenance, which can all be accessed through the Belimo assistant app, which makes the operations so smooth and easy to handle.
