Sensus 046-IRV-1 Gas Pressure Regulator 1 Inch Npt

Product Description

The SENSUS 046-IRV-1 is a gas pressure regulator designed for precise pressure control in commercial and industrial combustion systems. It features a 1-inch NPT connection and a 1/8-inch orifice optimized for stability in low-flow applications. The body is constructed from durable aluminum and handles an outlet pressure range of 8 to 20 psi. An integrated Internal Relief Valve (IRV) provides overpressure protection without requiring additional external piping in many configurations. Licensed gas technicians and combustion system installers routinely specify this regulator where fast response to load changes and a consistent set point under varying inlet pressures are required.

The 046-IRV-1 is suited for commercial and industrial natural gas service applications. Its 1-inch NPT connection fits standard service piping configurations encountered in boiler rooms, burner systems, and process combustion equipment. The integrated IRV makes it a practical choice where downstream overpressure protection must be compact and self-contained. It is appropriate for high-pressure service requirements where the outlet pressure must be held within the 8 to 20 psi range reliably across varying load conditions.

Key Features

• Integrated Internal Relief Valve (IRV) provides built-in overpressure protection without external piping
• Outlet pressure range of 8 to 20 psi for high-pressure service applications
• 1-inch NPT connection for compatibility with standard commercial and industrial gas piping
• 1/8-inch orifice optimized for stable regulation in low-flow conditions
• Aluminum body construction for durability in field installations
• Fast-acting response to load changes maintains consistent set point under varying inlet pressures

Compatibility

Designed as an OEM-style replacement or direct-install regulator for commercial and industrial natural gas combustion systems requiring a 1-inch NPT gas pressure regulator with an integrated internal relief valve.

Installation Notes

Installation should be performed by a licensed gas technician or pipefitter in accordance with applicable local codes and IFGC requirements. Shut off the gas supply completely and verify zero pressure in the line before removing or installing the regulator. Ensure pipe threads are clean and use approved thread sealant rated for natural gas service. Do not exceed the rated outlet pressure range or attempt to adjust the set point beyond the design limits of the regulator.
