Pro-source 4330221412PRO 3-way Palm Button Air Valve

Product Description

The PRO-SOURCE 4330221412PRO is a manually operated, mechanically actuated 3-way pneumatic air valve designed for use in compressed air control systems. The palm button actuator is spring-return style, meaning the valve shifts to its actuated position when the operator depresses the button and returns to its default position when released. With a Cv rating of 0.1 and NPT threaded ports, this valve is suited for low-flow pneumatic circuits requiring direct operator input. The red-colored button provides clear visual identification at the control point. Licensed pneumatic technicians and maintenance mechanics typically install and service this type of component.

This valve is commonly used in light-duty pneumatic circuits where a technician or operator needs direct manual control over airflow direction. Typical applications include small actuator control, pneumatic tool circuits, machine guarding interlocks, and test bench setups. The 3-way, 2-position configuration allows the operator to direct airflow between an inlet port and one of two working ports, making it appropriate for single-acting cylinder or exhaust-to-atmosphere functions in industrial and light manufacturing environments.

Key Features

• Palm button, spring-return actuation for momentary manual control
• 3-way, 2-position valve design for single-acting actuator or exhaust circuits
• Cv rating of 0.1 suitable for low-flow pneumatic applications
• NPT thread type for standard compressed air plumbing connections
• Red button color for easy visual identification at the operator interface
• Compact footprint at 1.77 inches wide and 3.29 inches tall

Compatibility

Designed as an OEM-style replacement or addition for manually controlled 3-way pneumatic valve positions in light-duty compressed air circuits with NPT-ported connections.

Installation Notes

Installation should be performed by a qualified pneumatic technician or maintenance mechanic familiar with compressed air system safety. Depressurize and lock out the pneumatic circuit before removing any existing valve or fitting. Use appropriate thread sealant rated for compressed air on all NPT connections and avoid over-tightening to prevent cracking the valve body. Verify system operating pressure and flow requirements are within the valve rating before returning the circuit to service.
