L2 Series 4-Way Solenoid Operated Pneumatic Valve, Single Solenoid Air Pilot, Spring Return w/Flush Locking Override, 1/4 Inch NPT Ports, 24 VDC Coil, Up To 79

For a 1/4 inch NPT valve, 79 SCFM is a solid flow rating. Most shop air applications running quarter-inch lines won't come close to pushing that hard, so you've got good headroom there. The Cv factor on this one is 1.7, which lines up well with the flow rating and confirms it moves air efficiently for its port size. As long as your system pressure stays between 14.5 and 150 PSIG on the shift side, this valve will cycle without issue.

This Numatics L Series valve is suitable for both unlubricated and lubricated service, so you shouldn't have any problems there.

For power and wiring, it uses a 24 VDC coil and comes with a DIN plug-in solenoid and plug connector that has an indicator light.
