The Namur solenoid valve is an electromechanical valve used in pneumatic actuator systems to direct airflow. These valves operate by changing the direction of pressurized air in response to an electrical signal from the system. Widely used in automation systems, they provide a fast and reliable control mechanism. Thanks to the Namur standard, they can be mounted directly onto actuator bodies, offering both ease of installation and sealing advantages.
Where is the Namur Solenoid Valve Used?
Namur solenoid valves are used across a wide range of industrial applications. Integrated with pneumatic actuator valves, these valves are considered an essential component of automation systems. They are particularly preferred in process control systems to direct airflow. In SCADA-based automation, they are used to directly control the open and closed positions of valves.
Additionally, when used together with 3-way ball valves, bypass operations can be easily performed. In industrial compressor systems, rapid air distribution is ensured, thereby increasing energy efficiency and enhancing control precision. HVAC systems, tank filling lines, and chemical process applications are also among the common areas of use.

Advantages and Ease of Use
One of the most notable advantages of Namur solenoid valves is that, thanks to their standard connection dimensions, they can be mounted directly onto any actuator. This significantly reduces installation time. Models designed for internal use can be safely operated under harsh conditions due to their protection class. Additionally, their lubrication-free design eliminates the need for maintenance.
Furthermore, compared to electric actuator systems, they operate with significantly lower energy consumption. This both reduces environmental impact and lowers long-term costs. For more information, you can consult the UNOX product catalog.
