This helps reduce external piping, simplify the air circuit, and save installation space. **5/2 Way Directional Air Control** The 5-port, 2-position structure makes the 4M310-08 suitable for controlling double-acting pneumatic actuators, rotary actuators, and cylinders in industrial automation systems. **Single Solenoid Control** The single solenoid design provides simple and reliable switching. When energized, the valve changes position; when de-energized, it returns to its normal state, making it suitable for repeated actuator operation. **1/4 Port for Stable Airflow** The 1/4 port size provides practical airflow capacity for medium pneumatic actuator systems, automated valve control, and general industrial air circuits. **Internal Pilot Structure** The internal pilot design supports sensitive response and stable operation under normal compressed air conditions. It helps improve switching reliability during continuous equipment operation. **Sliding Spool Design** The spool structure provides smooth movement, good sealing performance, and low friction, helping the valve maintain stable performance over long-term use. **No Extra Lubrication Required** The valve can operate in clean compressed air systems without additional oil lubrication, reducing maintenance work and keeping the pneumatic system cleaner. **Ideal Replacement for Airtac 4M300 Series Applications** The 4M310-08 can be selected for pneumatic actuator systems that require a NAMUR type 5/2 way solenoid valve compatible with Airtac 4M300 Series installations. ### Applications The 4M310-08 NAMUR solenoid valve is widely used in pneumatic actuator control, automated ball valves, butterfly valves, rotary actuators, double-acting cylinders, packaging machinery, process automation systems, industrial control panels, and factory automation equipment. It is especially suitable for applications where the solenoid valve needs to be mounted directly onto a pneumatic actuator through a NAMUR interface, helping reduce tubing, simplify installation, and improve the overall stability of the pneumatic control system. ### Why Choose HOMIPNEU HOMIPNEU supplies pneumatic solenoid valves for automation equipment, actuator control systems, valve automation projects, and industrial compressed air circuits.
