3/2-way and 5/2-way Namur solenoid valves for pneumatic systems
Precise control of the compressed air in pneumatic systems is the key to efficient system operation. The 3/2-way and 5/2-way Namur solenoid valves are among the components that enable this control. The function of these valves is many times more important for flow control in automation and industrial applications due to their reliability, compactness and compatibility with pneumatic actuators.
3/2-way Namur solenoid valves
The 3/2-way namur valve consists of three connections (inlet, outlet and exhaust) and two switching positions. It is used to control the air flow either to pressurise or to vent a single-acting cylinder or actuator. When the valve is switched on, the inlet for the air supply to the system is opened. Conversely, when the valve is switched off, the inlet is closed and the vent is opened so that the air can escape from the actuator, which would then extend using the spring force. They are used in applications that require simple on-off control, e.g. for clamping, lifting or positioning tasks in packaging machines or on assembly lines.
5/2-way Namur solenoid valves
A 5/2-way namur valve has five ports (inlet, two outlets, two vents) and two positions. This type of control valve is recognised by pneumatic users for its dynamic capabilities and its ability to change the sources of air flow in double-acting cylinders by pressurising and exhausting. The valve directs air to one outlet while exhausting the other side when energised. The reversal of the signal also reverses the direction of the air flow to the other outlet. This bi-directional control is particularly beneficial when operating robotic arms, material handling systems and processes that require repetitive motion in both directions.
The main advantages of Namur solenoid valves:
- Compact size: The Namur interface allows solenoid valves to be mounted directly on pneumatic actuators, saving space and hoses.
- Very fast: The solenoid switching guarantees a high response speed, which is important for fast automation.
- Robust: Designed to be resistant to dust and humidity or drastic temperature fluctuations in industrial environments.
- Compatible: The Namur solenoid valves fully comply with ISO 5211.

A Namur solenoid valve is an electrically controlled valve that controls pneumatic actuators. It is mounted directly on the actuator and enables precise control of the compressed air flow.
- Simple installation thanks to the Namur interface
- Reduction of external tubing
- Faster response times
- High reliability and durability
These valves are mainly used in automation technology, in the chemical industry, in water treatment and the food and pharmaceutical industries.
Namur solenoid valves are available in different versions, including 3/2-way and 5/2-way valves. Depending on the application, you can choose between monostable and bistable versions.
Yes, there are special explosion-proof (ATEX-certified) Namur solenoid valves that can be used in potentially explosive atmospheres.
It is mounted directly on the pneumatic actuator using a Namur interface. Electrical control is provided by a coil with a defined voltage (e.g. 24V DC or 230V AC).
These valves are mainly used for compressed air, but there are also special versions for other media such as gases or liquids.
- The quality of the compressed air (oil, water and dirt particles should be minimised)
- The frequency of switching operations
- The correct selection of voltage and coil
- Compliance with the manufacturer's operating parameters
