Parker 520411000 4-way 2-position Valve 1/4 Inch Npt

Product Description

The PARKER 520411000 is a 4-way, 2-position mechanically operated directional control valve with a button-spring return actuator. It features 1/4 inch NPT inlet and outlet ports and a Cv rating of 0.83, making it suited for controlling pneumatic or hydraulic actuators in industrial and commercial applications. The valve shifts when the button is depressed and returns to its original position via an internal spring when pressure is released. It is installed by fluid power technicians, automation specialists, and maintenance trades working with compressed air or compatible fluid systems.

This valve is commonly used in industrial automation, machine tool, and process control applications where a compact, manually triggered directional shift valve is required. Its 5-port configuration supports standard 4-way circuit routing. With a working pressure range of 0 to 150 psi and a temperature range of 32 to 175 degrees F, it fits a wide variety of light-to-medium duty pneumatic control circuits in both production and maintenance environments.

Compatibility

Designed as an OEM-style replacement or new-installation directional control valve for pneumatic systems using 1/4 inch NPT porting and operating within 0 to 150 psi working pressure limits.

Installation Notes

Installation should be performed by a qualified fluid power technician or maintenance professional familiar with pneumatic directional control circuits. Depressurize and lock out the pneumatic system before removing or installing any valve. Ensure all NPT thread connections are properly sealed with thread sealant compatible with the system media. Verify that system operating pressure and temperature do not exceed the rated limits of this valve before returning the system to service.
