Aro/ingersoll-rand M212SS-120-A 4-way Solenoid Valve 120V

Product Description

The ARO/INGERSOLL-RAND M212SS-120-A is a 4-way, 2-position stacking solenoid valve designed for directional control of pneumatic actuators and air-powered equipment. Operating on 120V AC with a Cv rating of 0.700 and a maximum flow rate of 30 cubic feet per minute, this valve delivers reliable, repeatable directional control in compressed air systems. The spring-return actuator design ensures the valve defaults to a safe position on power loss. It carries a NEMA 4 classification, making it suitable for use in wet or wash-down environments. Pneumatic controls technicians and maintenance professionals install this valve in industrial and commercial pneumatic circuits.

This valve is built for use in stacking pneumatic manifold assemblies where space-efficient directional control is required. The 1/4 inch inlet and 1/4 inch outlet ports fit standard pneumatic tubing and fittings common in factory automation, process control, and industrial air systems. Its compact 1.37-inch height makes it well-suited for manifold stack configurations with limited vertical clearance. The rated operating pressure range and temperature range support typical industrial compressed air supply conditions.

Installation Notes

Installation should be performed by a qualified pneumatic controls technician or industrial maintenance professional. Depressurize the air supply and de-energize all control circuits before removing or installing any solenoid valve. Verify that the supply voltage matches the coil rating of 120V AC before energizing the valve. Follow applicable local codes and the manufacturer's documentation for manifold assembly torque procedures and port sealing requirements.
