Parker PL50 4-way 3-position Manual Air Valve

Product Description

The PARKER PL50 is a manually operated 4-way, 3-position pneumatic directional control valve designed for controlling compressed air flow in industrial and commercial pneumatic systems. It features a hand throttle with manual return actuation via a lever, giving operators direct, positive control over valve positioning. With a Cv rating of 6.2 and NPT threaded connections, this valve is suited for moderate-flow pneumatic circuits where manual directional switching is required. Licensed technicians and industrial maintenance personnel are the typical installers of this component.

The PL50 fits applications in manufacturing, assembly, and process automation environments where pneumatic actuators, cylinders, or air tools require manual directional control. The 3-position configuration allows for mid-stroke hold or exhaust-center functions depending on circuit design. Its lever-based hand throttle with manual return makes it appropriate for intermittent-duty control stations, maintenance purge panels, and operator-controlled pneumatic circuits. Minimum working temperature is rated at 18 degrees F, making it suitable for cold-environment industrial installations.

Key Features

• 4-way, 3-position valve design for full directional control of pneumatic actuators
• Hand throttle with manual return actuation via lever for direct operator control
• Cv rating of 6.2 for moderate compressed air flow capacity
• NPT threaded connections for standard pneumatic plumbing integration
• Rated for operation down to 18 degrees F minimum working temperature

Compatibility

Designed as an OEM-style replacement or direct-install manual directional control valve for industrial pneumatic systems using NPT-threaded air circuit components.

Installation Notes

Installation of pneumatic directional control valves should be performed by qualified industrial maintenance technicians or pipefitters familiar with compressed air systems. Depressurize and lock out the air supply before removing or installing any valve in the circuit. Ensure all NPT fittings are sealed with appropriate thread sealant rated for pneumatic service, and verify the valve position function matches the circuit schematic before returning the system to service.
