Pro-source 5330221512PRO 3-way Air Valve Palm Button

Product Description

The PRO-SOURCE 5330221512PRO is a 3-way, 2-position directional control air valve designed for pneumatic circuit control in industrial and mechanical systems. Actuated by a palm button with spring return, it shifts between two positions to direct compressed air flow through the circuit. The valve carries a Cv rating of 0.298 and supports a maximum working pressure of 127.98 psi, with a rated flow of 7 SCFM. The 1/8 inch thread port size suits compact pneumatic assemblies. Installation and service are typically handled by industrial maintenance technicians, automation specialists, or experienced mechanical contractors.

This valve fits applications where manual operator control of a pneumatic actuator, cylinder, or air-operated device is required. The palm button actuator is common on machine guarding stations, press controls, and assembly line pneumatic circuits where the operator must apply deliberate hand force to shift the valve. The spring return ensures the valve automatically resets to its default position when the operator releases the button, which is standard practice in safety-conscious pneumatic designs. It is suited for light-duty compressed air systems operating within its rated pressure range.

Compatibility

Designed as a direct-replacement or new-installation 3-way 2-position palm button air valve for compact pneumatic circuits requiring 1/8 inch ported connections and operating pressures at or below 127.98 psi.

Installation Notes

Depressurize and lock out the pneumatic supply line before removing or installing any directional control valve. Apply thread sealant appropriate for compressed air service to the port threads, taking care not to allow sealant into the valve body. Verify the system operating pressure does not exceed the 127.98 psi maximum rating prior to commissioning. Consult applicable OSHA machine guarding and NFPA pneumatic safety standards when integrating palm button actuators into operator control stations.
