Pro-source 4550332010PRO 5-way Manual Hand Lever Valve

Product Description

The PRO-SOURCE 4550332010PRO is a manually operated 5-way directional control valve actuated by a hand lever with detent positioning. It delivers a Cv rating of 1.897, supporting reliable flow control in pneumatic systems. The lever detent mechanism locks the valve into each of its three positions, preventing unintended shifting during operation. Threaded NPT ports allow direct integration into standard pneumatic circuits. This valve is typically installed by industrial maintenance technicians, fluid power specialists, and mechanical contractors working on compressed-air control systems.

This valve is suited for pneumatic directional control applications in industrial, manufacturing, and automation environments. Its 5-way, 3-position design makes it appropriate for controlling double-acting cylinders or other actuators that require full directional authority, including stopped mid-stroke capability. The compact footprint fits panel-mount or manifold-style installations where manual operator control is preferred over solenoid or pilot actuation.

Key Features

• 5-way, 3-position directional control for double-acting pneumatic actuators
• Hand lever with lever detent holds selected position without continuous operator force
• Cv rating of 1.897 for consistent flow performance
• NPT thread type for compatibility with standard pneumatic and fluid power fittings
• Compact body measuring 4.49 inches long, 1.81 inches wide, and 4.13 inches tall

Compatibility

Designed as an OEM-style manual directional control valve for standard NPT-ported pneumatic systems requiring 5-way, 3-position hand-lever actuation.

Installation Notes

Installation should be performed by a qualified fluid power or pneumatic systems technician. Depressurize the pneumatic circuit fully and lock out the compressed-air supply before removing or installing any directional control valve. Verify NPT thread engagement and use appropriate thread sealant compatible with the system media. Confirm that the Cv rating of the selected valve meets the flow demand of the downstream actuator before finalizing installation.
