Sensus 496-20-1 Regulator

The Sensus 496-20-1 Regulator is a high-performance domestic service regulator engineered for residential, light commercial, and industrial gas applications. Built with a 1-inch NPT straight body and a 1/4-inch orifice, this unit is designed to handle a maximum inlet pressure of up to 60 PSIG while maintaining precise downstream control. The Green spring provides a stable outlet pressure range of 6-14 inches W.C., making it an ideal choice for natural gas, propane, and other non-corrosive gases. Featuring a 4-inch roll-out diaphragm, the 496 series delivers the flow capacity typically reserved for larger 6-inch diaphragm models within a more compact footprint. This specific configuration includes an Internal Relief Valve (IRV) to protect equipment from over-pressure conditions, ensuring consistent positive dead-end lockup and reliability for critical burner and furnace installations. Every component, from the cast iron body to the reinforced Buna-N diaphragm, is selected for long-term durability in field conditions.

• Optimized Performance: The 4-inch roll-out diaphragm technology provides high flow capacity and superior sensitivity to pressure fluctuations.
• Internal Safety: Standard Internal Relief Valve (IRV) enhances system safety by venting excess pressure during surges.
• Rugged Construction: Durable cast iron valve body and die-cast aluminum spring case offer robust protection against environmental demands.
• Versatile Installation: The 1-inch NPT connection and 360-degree rotating diaphragm case allow for flexible mounting in tight service enclosures.

Common Questions:

What is the maximum inlet pressure for a 1/4-inch orifice?
For the Sensus 496-20-1 configured with a 1/4" orifice, the recommended maximum inlet pressure is 60 PSIG to ensure optimal regulation performance.

Can this regulator be used for propane service?
Yes, the Sensus 496 is a general-purpose regulator compatible with natural gas, LP gas (propane), air, and nitrogen.

How do I adjust the outlet pressure within the 6-14" W.C. range?
The outlet pressure is adjusted by removing the top closing cap and turning the adjustment screw; turning clockwise increases the pressure setpoint.
