Parker 524811000 3-way 2-position Valve 1/4 Inch Npt

Product Description

The PARKER 524811000 is a 3-way, 2-position mechanically operated valve designed for directional flow control in pneumatic and fluid systems. It uses a lever-spring return actuator, which shifts the valve manually and automatically returns it to the default position when released. The valve has a Cv rating of 0.83 and supports working pressures from 0 to 150 psi. With 1/4 inch NPT threaded inlet and outlet ports, it integrates directly into standard pipe and fitting assemblies. Licensed plumbers, pipefitters, and fluid-system technicians typically install and service this type of directional control valve.

This valve is suited for industrial and commercial fluid control applications where a manually actuated, self-returning directional valve is required. Common install scenarios include machine tool circuits, pneumatic actuation systems, and process-line diversion applications. It operates across a temperature range of 32 degrees F to 175 degrees F, making it appropriate for a wide range of indoor industrial environments. The lever actuator allows hands-on, repeatable actuation without requiring an electrical signal or pilot pressure source.

Key Features

• 3-way, 2-position flow path for reliable directional control
• Lever-spring return actuator for manual operation with automatic reset
• 1/4 inch NPT threaded inlet and outlet for standard pipe compatibility
• Cv rating of 0.83 for controlled flow capacity
• Operating pressure range of 0 to 150 psi
• Temperature-rated from 32 degrees F to 175 degrees F

Compatibility

Designed as an OEM-style directional control valve for pneumatic and fluid systems requiring a 3-way, 2-position, lever-spring return actuated valve with 1/4 inch NPT connections and a maximum working pressure of 150 psi.

Installation Notes

Installation should be performed by a qualified pipefitter or fluid-systems technician. Depressurize and isolate the system completely before removing any existing valve or fitting. Apply thread sealant appropriate for the media type to all NPT connections and torque fittings to the fitting manufacturer's specification. Verify flow direction and port assignment against the system schematic before returning the line to service.
