INTRODUCTION:
What Is A Namur Solenoid Valve. The function of a namur solenoid valve is to control media flow: These include dosing and releasing, mixing and distributing, and shutting off the supply of gases, liquids and bulk materials, such as powders or grains. A namur solenoid valve is a type of valve designed to be mounted on pneumatic actuators using the standardized namur interface. Namur is a standard that applies to pneumatic solenoid valves and some electrical parts associated with pneumatics. The function of a namur solenoid valve is to control media flow: User association of automation technology in process industries. The valve itself is controlled by an electric solenoid, which opens or closes the valve, by controlling the amount of. Namur valves are used as pilot valves to control the actuator in many flow processes. What is a namur solenoid valve? It is an acronym stemming from the organisation in germany that chartered this standard: In addition, there are holes for fixing.

TECHNICAL ADVANTAGES:
Classic, Reliable Sliding Column: The 4M uses a "Sliding Column" (Spool) structure. Unlike some other designs, a spool is "pressure-balanced." This means its "sensitive reaction" and response time are predictable and stable, even if your main air pressure fluctuates. In process control, that kind of consistency is gold.
Low-Friction, Long-Life & No-Lube: The 4M's "special inner hole processing" makes it super low-friction. This not only gives it a long life and a low 0.15MPa start-up pressure, but it also means it's "no need to add oil" certified. This is a huge deal for food, pharma, painting, or electronics lines where oil mist is a contaminant.
Scalable Flow (Choose Your Power): The 4M is a full family. You can scale the flow to the job:
4M100 Series (Cv=0.6) for small actuators.
4M200 Series (Cv=1.0) for the mid-range workhorses.
4M300 Series (Cv=1.65) when you need more speed and power.
Advanced Control ("Memory Function"): The 4M is a 5/2-Way valve, the standard for double-acting actuators (which need air to open and close). It gives you two critical control logics:
Single Solenoid (e.g., 4M210): Spring-return. Power off, it springs back. This is for 'Fail-Safe' (e.g., 'fail-closed') applications.
Double Solenoid (e.g., 4M220): This is the "memory function." No spring. It holds its last position even if power is cut. This is 'Fail-in-Place' or 'Stay-Put,' which is critical for preventing a batch from being ruined by a power blip.
