Parker 410211000 4-way 2-position Valve 1/8 Inch Npt

Product Description

The PARKER 410211000 is a mechanically operated 4-way, 2-position directional control valve designed for pneumatic circuit applications. It uses a roller lever actuator with spring return, meaning the valve shifts when the roller lever is physically contacted by a cam or mechanical stop and returns to its original position automatically when the actuating force is removed. The valve features a 1/8 inch NPT inlet, a Cv rating of 0.200, and a maximum working pressure of 150 psi. It has 5 ports and is suited for compact pneumatic control systems where mechanical position sensing or limit detection is required.

This valve is typically installed in industrial pneumatic systems where directional control must be triggered by physical machine movement rather than an electrical signal. Common applications include end-of-stroke detection, safety interlocks, and sequencing circuits on production equipment, automation machinery, and pneumatic actuator systems. It is appropriate for environments where operating temperatures remain between 32 degrees F and 175 degrees F. Installation is performed by pneumatic system technicians or maintenance mechanics.

Key Features

• 4-way, 2-position directional control valve for pneumatic circuit switching
• Roller lever actuator with spring return for automatic reset when force is removed
• 1/8 inch NPT inlet for compact pneumatic line integration
• Cv rating of 0.200 suitable for small-bore pneumatic circuits
• Operating pressure range of 0 to 150 psi
• 5-port configuration supporting standard directional control plumbing

Compatibility

Designed as an OEM-style replacement or direct-install mechanically operated directional control valve for pneumatic systems utilizing 1/8 inch NPT connections and requiring a 4-way, 2-position roller lever spring-return actuator.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or industrial maintenance mechanic. Depressurize and lock out the pneumatic system before removing or installing any valve. Verify that all port connections are made with properly rated NPT fittings and thread sealant appropriate for pneumatic service. Do not exceed the rated working pressure of 150 psi or operate outside the specified temperature range.
