Pro-source 4550331011PRO 5-way Hand Lever Valve 0.976 Cv

Product Description

The PRO-SOURCE 4550331011PRO is a manually operated 5-way, 3-position directional control valve actuated by a hand lever with detent positioning. It is designed for pneumatic circuit control in industrial and mechanical systems where manual switching of airflow direction is required. The valve carries a Cv rating of 0.976 and uses NPT threaded port connections. With its lever detent mechanism, the actuator holds its selected position without continuous operator input, making it suitable for applications that require a stable, locked flow state between cycles. Installation is typically performed by industrial maintenance technicians or mechanical system integrators.

This valve is well suited for pneumatic automation systems, machine tool controls, and other compressed-air-driven equipment requiring manual directional switching. Its 5-way, 3-position configuration supports applications such as double-acting cylinder control with a center exhaust, pressure, or blocked center condition. The compact body dimensions make it a practical fit in panel-mounted or inline installations where space is limited.

Key Features

• 5-way, 3-position valve design for versatile pneumatic circuit configurations
• Hand lever actuation with detent holds selected position without continuous force
• Cv rating of 0.976 for consistent, predictable flow performance
• NPT threaded ports for standard pipe and fitting compatibility
• Compact form factor suitable for inline or panel-mount installations

Compatibility

Designed as an OEM-style replacement or direct-fit component for pneumatic directional control circuits using standard NPT-ported 5-way manual valves.

Installation Notes

Installation should be performed by a qualified industrial maintenance technician or pneumatic systems specialist. Depressurize the pneumatic circuit fully before removing or installing any valve component. Verify NPT thread compatibility and use appropriate thread sealant on all connections per applicable plumbing and pneumatic system standards. Do not exceed the rated Cv or system pressure specifications for the circuit in which this valve is installed.
