Direct Mount 5/2 Way Pneumatic Solenoid Valve 4m Series Single Coil Double Coil with Memory Function G1/4 G3/8

Single-coil (monostable) valves have one solenoid coil and a spring return mechanism. When power is applied, the valve switches position; when power is removed, the spring returns the valve to its original position. This is ideal for spring-return actuators. Double-coil (bistable) valves have two solenoid coils and feature memory function - each coil switches the valve to a specific position, and the valve maintains that position even after the electrical signal is removed. This is ideal for dou

NAMUR is an international standard for valve automation that defines mounting interfaces, dimensions, and performance characteristics for solenoid valves used with pneumatic actuators. The 4M series complies with NAMUR/VDI/VDE3845 standards, meaning it can be directly mounted onto NAMUR-compliant actuators without additional brackets or tubing. This simplifies installation, reduces potential leak points, and ensures interchangeability with other NAMUR-standard equipment from different manufactur

The 4M series features internally piloted structure, sliding column spool design for excellent sealing and sensitive response, special internal hole processing for low friction and long service life, lubrication-free operation, manual override device for debugging, and IP65 protection. Double-coil versions also have memory function, maintaining their position after power removal.

The 4M series is specifically designed for controlling pneumatic actuators in industrial automation systems, including: Actuated ball valves and butterfly valves in process control On/off valve automation in water treatment, chemical, and oil/gas industries Rotary cylinder control in packaging and assembly machinery Automated valve systems requiring NAMUR interface compatibility OEM applications for valve actuator manufacturers

Operating pressure range is 0.15 0.8MPa (21 114 psi). Maximum proof pressure is 1.2MPa (175 psi). Operating temperature range is -20C to 70C(-4F to 158F), making it suitable for both cold and hot industrial environments.
