Norgren R18-C05-RNLA Air Regulator 2000 Cfm 2in Npt 450 Psi

Product Description

The NORGREN R18-C05-RNLA is a hi-flow pilot operated compressed air regulator built for high-demand industrial and commercial pneumatic systems. It accepts a 2-inch NPT port connection and handles supply pressures up to 450 psi, making it suitable for heavy-duty air distribution applications where pressure control and high volume flow are both required. With a rated airflow capacity of 2000 CFM and an adjustable output range of 5 to 125 psi, this regulator is installed by industrial mechanics, pipefitters, and compressed air system technicians in facilities that run large pneumatic tools, automation equipment, or process air lines.

This regulator is designed for compressed air service in industrial environments where high flow rates are critical to downstream system performance. The hi-flow pilot operated design maintains stable outlet pressure even under significant flow demand variations. A built-in relief function allows excess pressure to vent, protecting downstream components. The regulator is rated for operating temperatures down to 0 degrees F, supporting use in cold storage facilities, outdoor installations, or unheated industrial spaces. A 1/4-inch gauge port is included for field installation of a pressure gauge, though a gauge is not included with this unit.

Key Features

• Hi-flow pilot operated design rated at 2000 CFM for high-demand pneumatic systems
• 2-inch NPT port size for integration into large-diameter compressed air mains
• Maximum supply pressure of 450 psi with adjustable output range of 5 to 125 psi
• Built-in relief function vents excess downstream pressure automatically
• 1/4-inch gauge port for field-installed pressure monitoring
• Aluminum body construction for corrosion resistance and reduced weight
• Rated for minimum operating temperature of 0 degrees F

Compatibility

Designed as an OEM-style replacement or direct-install regulator for industrial compressed air distribution systems requiring a 2-inch NPT connection and hi-flow pilot operated pressure regulation.

Installation Notes

Installation should be performed by a qualified pipefitter or compressed air systems technician in accordance with applicable local codes and OSHA compressed air safety requirements. Depressurize and lock out the air supply line completely before installing or removing the regulator. Apply appropriate thread sealant to NPT connections and verify all joints are leak-free before returning the system to service. Do not exceed the 450 psi maximum supply pressure rating under any operating condition.
