Product Overview
The AirTAC 4M310-08 is a 5/2-way NAMUR-mount pneumatic solenoid valve engineered for direct pilot actuation of quarter-turn pneumatic actuators and double-acting cylinders. As part of the AirTAC 4M series, this valve utilizes a precision spool-and-sleeve design with a NAMUR interface (VDI/VDE 3845) that allows direct mounting to standard pneumatic actuator pads without additional piping or adapter plates. The 4M310-08 is a single-solenoid, spring-return configuration, meaning the valve shifts to the energized position when the solenoid is powered and automatically returns to the de-energized position upon signal loss, providing fail-safe operation. With an 08 (1/4″) port size, this valve is suited for moderate-flow pneumatic circuits in process automation, packaging machinery, and industrial valve actuation systems.
