Norgren 11-042-007 Air Pilot Operated Regulator 3/4 Npt

Product Description

The NORGREN 11-042-007 is an air pilot operated compressed air regulator designed for high-pressure pneumatic systems requiring precise downstream pressure control without direct manual adjustment at the regulator body. Rated to 400 psi maximum supply pressure with a control range of 10 to 400 psi, it handles up to 142 CFM of compressed air flow through a 3/4 inches NPTF port. The regulator includes a built-in relief function, allowing excess downstream pressure to vent when the pilot signal drops. It is installed by industrial maintenance technicians and pneumatic system specialists working on compressed air distribution lines, automation equipment, and process control applications.

The 11-042-007 fits into compressed air systems where the regulator must be controlled remotely or sequenced by a pneumatic pilot signal rather than a manual handknob. Typical installations include multi-zone pneumatic circuits, press and actuator control panels, and production line air systems where consistent, remotely governed pressure is required. The 3/4 inches NPTF end connections suit standard iron or steel compressed air piping. A 1/2 inches gauge port thread is provided if a downstream pressure gauge is added in the field, though no gauge is included with this unit.

Key Features

• Air pilot operated control for remote pressure regulation without manual adjustment at the valve body
• 400 psi maximum supply and working pressure with a 10 to 400 psi adjustment range
• 142 CFM maximum air flow capacity through 3/4 inches NPTF ports
• Integrated relief function vents excess downstream pressure on pilot signal drop
• 1/2 inches gauge port thread for optional field-installed pressure gauge
• Zinc and aluminum construction for durability in industrial pneumatic environments

Compatibility

Part of the NORGREN 11-042 series. Designed for compressed air service with NPTF-threaded piping at 3/4 inches port size. Verify pilot signal pressure range and downstream system requirements before installation.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or industrial maintenance professional. Depressurize and lock out the compressed air supply before removing any existing regulator or making piping connections. Apply thread sealant rated for compressed air service to all NPTF connections and verify joint integrity before re-pressurizing. Confirm that the pilot signal source and downstream components are rated for the full 400 psi working pressure of this regulator.
