Parker 410111000 4-way 2-position Valve 1/8 Inch Npt

Product Description

The PARKER 410111000 is a mechanically operated directional control valve designed for pneumatic systems requiring precise 4-way, 2-position flow control. The valve features a plunger actuator with spring return, meaning it shifts to the active position when the plunger is depressed and returns to its default state automatically when released. With a Cv rating of 0.200 and a maximum working pressure of 150 psi, this compact valve suits applications where controlled airflow direction is critical. It is installed by industrial maintenance technicians, pneumatic system integrators, and experienced mechanical trades.

This valve is suited for light-duty pneumatic circuit applications in industrial, manufacturing, and automation environments. The 1/8 inch NPT inlet port keeps the footprint small, making it a practical choice for panel-mounted or machine-integrated pneumatic assemblies. It operates across a working temperature range of 32 degrees F to 175 degrees F, supporting year-round use in both indoor and climate-controlled industrial settings. The spring-return actuator design is common in safety-oriented circuits where the valve must default to a known position without power or manual intervention.

Key Features

• 4-way, 2-position directional control for pneumatic circuits
• Plunger actuator with spring return for automatic default positioning
• 1/8 inch NPT inlet for compact installation footprint
• Cv rating of 0.200 for controlled low-flow pneumatic applications
• Operating pressure range of 0 to 150 psi
• 5-port configuration supporting standard 4-way circuit layouts

Compatibility

Designed as an OEM-style replacement or new-installation directional control valve for light-duty pneumatic circuits using 1/8 inch NPT ported components.

Installation Notes

Installation should be performed by a qualified pneumatic technician or industrial maintenance professional. Depressurize and isolate the pneumatic circuit completely before removing or installing any valve. Verify all port connections are sealed with appropriate thread sealant compatible with pneumatic service before restoring system pressure. Confirm actuator plunger travel is unobstructed and that the spring-return function cycles freely prior to returning the system to operation.
