The Numatics 031SA4412000030 is an electrically actuated pneumatic solenoid valve from the Mark 3 Series that provides precise 2-position, 4-way (5/2) directional control for industrial air systems. Single solenoid actuation with spring return drives the spool and sleeve mechanism to regulate flow across 1/8″ NPTF ports. Rated to 150 PSIG maximum operating pressure with a flow coefficient of 0.35, this valve delivers 8.34 to 16.21 SCFM at 80 PSIG and operates across a pressure range from 28″ HG vacuum to 150 PSIG. The DIN plug-in solenoid accepts 110–120 VAC at 50/60 Hz with minimal power draw of 5.5 W and holding current of 0.063 A. Rated NEMA 4 protection ensures reliable performance across ambient temperatures from −10°F to +115°F. CE marked for compliance.
