Norgren 03040022 Mechanically Operated Valve 1/8 Inch Npt

Product Description

The NORGREN 03040022 is a mechanically operated, packed spool directional control valve designed for pneumatic system control in industrial and trade applications. It uses a plunger actuator to shift a 3-port, 2-position spool, with a spring return to restore the valve to its default position when the actuator is released. The valve has a Cv rating of 0.340 and accepts a 1/8 inch NPT inlet connection. It is rated for a maximum working pressure of 10 bar and operates across a temperature range of 32 degrees F to 158 degrees F. Pneumatic system technicians and industrial maintenance professionals install this valve in compressed air circuits requiring reliable mechanical actuation and repeatable flow control.

This valve fits into compact pneumatic control assemblies where mechanical actuation is preferred over electrical solenoid operation. Typical applications include machine guarding, actuator sequencing, and position-sensing circuits in manufacturing and automated equipment environments. The 1/8 inch NPT inlet makes it compatible with standard small-bore pneumatic plumbing commonly found in light industrial and OEM equipment builds. Its black housing and packed spool design suit environments where consistent sealing and low-maintenance operation are priorities.

Key Features

• Packed spool design provides reliable sealing across the operating pressure range
• Plunger actuator enables direct mechanical actuation from cams, levers, or contact surfaces
• Spring return automatically restores valve to default position when actuator force is removed
• 1/8 inch NPT inlet fits standard small-bore pneumatic plumbing
• Cv rating of 0.340 suited for low-flow pneumatic control circuits
• Rated to 10 bar maximum working pressure
• Operating temperature range of 32 degrees F to 158 degrees F

Compatibility

Designed as an OEM-style replacement or new-installation directional control valve for compact pneumatic circuits using 1/8 inch NPT connections and spring-return mechanical actuation.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician. Depressurize and lock out the pneumatic supply before removing any existing valve or making connections. Use thread sealant rated for compressed air service on all NPT connections and torque fittings according to the fitting manufacturer's specifications. Verify that system pressure does not exceed the 10 bar maximum rating before returning the circuit to service.
