Pro-source 4330224512PRO 3-way Palm Button Air Valve

Product Description

The PRO-SOURCE 4330224512PRO is a manually operated, mechanically actuated 3-way pneumatic air valve designed for direct hand-actuation in compressed air control applications. The palm button actuator allows an operator to shift valve positions with a single downward press, making it well-suited for press safety circuits, workstation air control, and machine guarding interlocks. The valve carries a Cv rating of 0.1, placing it in the low-flow category for pilot signal or small actuator duties. NPT threaded ports ensure compatibility with standard pipe fittings common in North American pneumatic systems. Licensed trades and industrial maintenance technicians are the typical installers.

This valve is used in light industrial and production environments where a compact, manually triggered directional control point is needed. Typical applications include pneumatic press controls, foot-or-hand-initiated pilot circuits, and machine tool air logic where a 3-way, 2-position configuration is required. The red color provides visual identification on panel-mounted or manifold-mounted assemblies. Its small footprint suits installations with limited mounting space on control stands, junction boxes, or pneumatic subplates.

Key Features

• Palm button actuator allows single-hand, downward-press operation without tools
• 3-way, 2-position valve design directs or exhausts air flow on demand
• 0.1 Cv rating suited for pilot signal lines and small-bore actuator circuits
• NPT thread type for straightforward connection to standard North American pipe fittings
• Red body color aids visual identification in multi-valve panel layouts
• Compact form factor at 3.4 inches tall and approximately 1.77 inches wide

Compatibility

Designed as a direct-fit manually operated 3-way palm button pneumatic valve for light industrial compressed air control systems using NPT threaded connections. No specific OEM system compatibility data was provided by the manufacturer for this part number.

Installation Notes

Installation is typically performed by a qualified industrial maintenance technician or pneumatic systems mechanic. Depressurize and lockout the compressed air supply completely before removing or installing any pneumatic valve. NPT threads should be sealed with thread tape or pipe sealant rated for compressed air service and tightened to fitting manufacturer guidelines without over-torquing. Verify that line pressure and flow requirements fall within the valve rating before returning the circuit to service.
