Sensus 496-20-3/8 Regulator

The Sensus 496-20-3/8 Regulator is a robust domestic service regulator engineered for residential, light commercial, and industrial gas applications. Designed to handle natural gas, LPG, and other non-corrosive vapors, this model features a 3/8" NPT inlet/outlet and a 1/4" orifice, supporting a maximum inlet pressure of up to 60 psig. The green spring provides a precise 6-14" W.C. outlet pressure range, making it an ideal solution for balancing downstream demand across burners, furnaces, and unit heaters. Utilizing a 4" roll-out diaphragm, the 496 series delivers high-capacity performance typically found in larger 6" units, while the internal relief valve (IRV) ensures overpressure protection by venting 7-10" W.C. above the set point. Constructed with a cast iron valve body and a die-cast aluminum case, this pilot-ready regulator offers 360-degree mounting flexibility and long-term durability in demanding outdoor environments.

Key Benefits

• High Capacity Small Footprint: The 4" roll-out diaphragm provides flow capacities equivalent to larger 6" diaphragm regulators, perfect for tight residential meter sets.
• Integrated Safety: Features a standard internal relief valve (IRV) for superior overpressure protection without requiring additional external hardware.
• Operational Versatility: Compatible with natural gas, propane, air, and dry CO2; the 496-20 straight body design simplifies inline installation.
• Industrial Grade Build: Cast iron body construction and chromate-converted castings with enamel topcoats prevent corrosion in harsh service conditions.

Common Questions

• What is the maximum inlet pressure for the 1/4" orifice? With the 1/4" aluminum orifice installed, the Sensus 496 is rated for a maximum inlet pressure of 60 psig.
• Can this regulator be installed vertically? Yes, the diaphragm case can be rotated 360 degrees in 90-degree increments to accommodate various piping configurations; ensure the vent is pointed downward in outdoor setups.
• What is the relief point of the internal valve? The internal relief valve is factory-set to begin relieving at approximately 7-10" W.C. above your normal outlet pressure setting.
