Parker 414211000 3-way 2-position Valve Roller Lever 1/8 Npt

Product Description

The PARKER 414211000 is a 3-way, 2-position mechanically operated valve designed for pneumatic and fluid control applications. It uses a roller lever actuator with spring return, meaning the valve shifts when the roller contacts a cam or trip dog and automatically returns to its original position when contact is released. The valve features a 1/8 inch NPT inlet, a Cv rating of 0.200, and a maximum working pressure of 150 psi. At 0.5 pounds, it is a compact inline component suited for machine builders, automation technicians, and maintenance professionals working on pneumatic circuits.

This valve is typically installed in industrial and light commercial pneumatic systems where mechanical actuation from a moving machine element is needed to shift flow between ports. Common applications include end-of-stroke sensing, door or guard interlocks, and sequence control logic in pneumatic circuits. The spring return function ensures a defined fail-safe position when the actuator is not engaged. It is rated for operating temperatures from 32 degrees F to 175 degrees F, making it suitable for most indoor industrial environments.

Key Features

• 3-way, 2-position valve configuration for directional flow control
• Roller lever actuator with spring return for reliable mechanical actuation
• 1/8 inch NPT inlet for straightforward inline installation
• Cv rating of 0.200 for low-flow pneumatic circuit applications
• Operating pressure range of 0 to 150 psi
• Compact and lightweight at 0.5 pounds for space-constrained installations

Compatibility

Designed as an OEM-style replacement or new-installation component for pneumatic control circuits requiring a 3-way, 2-position mechanically operated valve with a 1/8 inch NPT port and roller lever-spring return actuation.

Installation Notes

Installation should be performed by a qualified automation or pneumatic systems technician. Depressurize and lock out the pneumatic supply before removing or installing any valve component. Ensure NPT threads are properly sealed with thread sealant appropriate for the fluid media. Verify that the roller lever is aligned correctly with the actuating cam or trip dog to achieve consistent, repeatable actuation.
