Sensus 143-80-6-3/4 Regulator
The Sensus 143-80-6-3/4 Regulator is a specialized domestic and light commercial gas service regulator engineered for high-precision pressure management in critical HVACR applications. This specific model features a low pressure cut-off (LPCO) mechanism, providing an essential safety layer that automatically terminates gas flow if the inlet pressure drops below the required threshold for safe operation. Built with a 5/16" orifice and 3/4" NPT connections, it is optimized for high-performance stabilization of natural gas, propane, air, or CO2. Its robust cast iron body and die-cast aluminum diaphragm case are designed to withstand service regulator demands in burners, boilers, and unit heaters.
For technical versatility, the 7.5-15" w.c. outlet pressure range is managed by a green spring, ensuring consistent positive dead-end lockup even under fluctuating demand. The union nut connection allows for 360-degree diaphragm rotation, streamlining natural gas regulator installation in tight mechanical rooms or vertical piping runs. Contractors rely on the Sensus 143 series for its precision-fit polyethylene valve and nylon fabric-reinforced Buna-N diaphragm, which maintain structural integrity across an operating temperature range of -20°F to 150°F.
Key Benefits for Technicians:- Automatic Safety Integration: The low pressure cut-off (LPCO) protects downstream equipment from hazardous low-pressure conditions without requiring external power.
- Advanced Flow Control: Equipped with a 5/16" orifice for high-capacity flow while maintaining stable 7.5-15" w.c. outlet pressure.
- Field Versatility: Features a 3/4" NPT cast iron regulator body with a union nut design for effortless 360° positioning.
- Reliable Construction: Internal components include a stainless steel fulcrum pin and fiberglass-reinforced nylon stem for durability in rigorous environments.
- Environmental Protection: Cases are dip-primed with a chromate conversion coating and finished with enamel for superior corrosion resistance.
- How do I reset the LPCO after a shutdown? You must manually reset the LPCO by removing the spring cap and pulling up the internal pin once the appropriate inlet pressure is restored.
- Can this regulator be used for propane? Yes, the 143-80-6 is compatible with propane (LPG), natural gas, air, CO2, and other non-corrosive technical gases.
- In what orientation should the vent be installed? For outdoor installations, the 1" NPT vent must face downward to prevent moisture, ice, or debris from obstructing the diaphragm movement.
