Sensus 046-IRV-1 Regulator

The Sensus 046-IRV-1 is a high-performance industrial gas regulator designed for precise pressure control in commercial and industrial combustion systems. This model features a 1-inch NPT connection and is equipped with a 1/8-inch orifice, optimized for stability in low-flow applications. Constructed with a durable aluminum body, it handles an outlet pressure range of 8 to 20 PSI, making it ideal for high-pressure service requirements. The integrated Internal Relief Valve (IRV) provides essential overpressure protection, ensuring system safety without the need for additional external piping in many configurations. Technicians frequently spec the Model 046 regulator for its fast-acting response to load changes and its ability to maintain a consistent set point under varying inlet pressures. This Sensus gas pressure regulator is a standard choice for natural gas service where rugged reliability and field-proven accuracy are non-negotiable requirements for downstream equipment performance.

• Internal Relief Valve: The Sensus IRV mechanism minimizes installation complexity by providing built-in relief capacity.
• Precise Pressure Regulation: Engineered to hold tight tolerances within the 8-20# spring range for sensitive burner manifolds.
• Corrosion Resistance: The aluminum construction offers a high strength-to-weight ratio and resilience against harsh environment exposure.
• Field Serviceability: Designed for straightforward diaphragm and orifice inspection, reducing downtime during routine maintenance.

Common Questions

What is the maximum inlet pressure for the 046-IRV-1?
The Sensus 046-IRV-1 maximum inlet pressure is typically rated up to 125 PSIG, though actual capacity depends on the specific orifice size and required droop characteristics.

Can this regulator be used for Propane (LPG) service?
Yes, the materials are compatible with LPG vapor, but capacities must be recalculated based on the specific gravity of the gas being regulated.

How do I adjust the outlet pressure on the 8-20 PSI spring?
Adjustments are made via the top adjustment screw; rotating clockwise increases the compression on the regulator spring to raise the outlet set point.
