Norgren 11-042-008 Air Regulator 1 Inch Npt 400 Psi

Product Description

The NORGREN 11-042-008 is an air pilot operated compressed air regulator rated for up to 400 psi supply pressure with a 1-inch NPTF port connection. It delivers a maximum air flow of 142 CFM and is built from zinc and aluminum construction for durability in demanding industrial environments. The regulator includes a relief function for safe downstream pressure management and is designed for installation by licensed pipefitters, industrial maintenance technicians, and mechanical contractors working on compressed air distribution systems. The operating temperature range starts at 0 degrees F, making it suitable for cold-environment applications.

The 11-042-008 is suited for industrial and commercial compressed air systems where remote or automated pressure regulation is required. Air pilot operation allows the regulator to be controlled by a separate pilot signal, making it a practical choice for automated process lines, pneumatic control systems, and high-pressure distribution headers where manual adjustment is not practical. The 1-inch port size and 400 psi maximum working pressure support high-volume, high-pressure applications across manufacturing, processing, and heavy mechanical service environments.

Key Features

• Air pilot operated design enables remote pressure control without manual adjustment
• Rated to 400 psi maximum supply and working pressure
• Maximum air flow of 142 CFM at rated conditions
• 1-inch NPTF end connection for standard compressed air piping integration
• Built-in relief function protects downstream components from overpressure
• Zinc and aluminum construction balances strength and weight
• Operating range down to 0 degrees F supports cold-environment installations

Compatibility

Designed as an OEM-style replacement or new-installation regulator for industrial compressed air systems requiring 1-inch NPTF porting and air pilot operation at pressures up to 400 psi. Part of the NORGREN Series 11-042 regulator family.

Installation Notes

Installation should be performed by a qualified pipefitter or mechanical technician familiar with compressed air system codes and safe pressure handling procedures. Depressurize and lock out the compressed air supply completely before removing or installing the regulator. Verify that downstream system components are rated for the full supply pressure before commissioning. Apply appropriate thread sealant to NPTF connections and confirm all fittings are leak-free before returning the system to service.
