Sensus 243-RPC-A-2 Regulator

The Sensus 243-RPC-A-2 is a heavy-duty, pilot-operated industrial gas regulator engineered for high-capacity applications requiring extreme precision. Featuring a 2" NPT connection and a 3/4" 30-degree orifice, this model utilizes a relay principle of operation to maintain a stable 1-5 PSIG outlet pressure, regardless of inlet fluctuations up to 125 PSIG. The "A" designation signifies its requirement for an external control line (typically 30 feet in this configuration) to sense downstream pressure accurately, making it the standard choice for fixed factor billing and pressure factor measurement.

Built with a rugged cast iron body and a white spring for 1-5 PSIG calibration, this pilot-operated regulator is optimized for natural gas service as well as LPG, nitrogen, and dry CO2. Technicians favor the 243-RPC for its ability to hold outlet pressure within ±0.5% of the absolute setpoint, ensuring consistent performance for large burners, boilers, and industrial furnaces. This unit is designed for durability in demanding environments but is not rated for buried service.

• Superior Precision: Pilot-operated relay principle provides ±0.5% accuracy from minimum flow to wide-open capacity.
• High Inlet Handling: Safely manages up to 125 PSIG maximum inlet pressure with consistent delivery.
• Customizable Configuration: Features a 3/4" orifice and white spring for a 1-5 PSIG range, suitable for commercial gas distribution.
• Versatile Media Compatibility: Performs reliably with natural gas, air, propane, and inert gases.
• Field Serviceable: Union connection design allows for easier inspection and maintenance of internal components.

• Does this model require an external control line? Yes, the 243-RPC-A is designed for external sensing to maximize accuracy and requires a dedicated control line piped downstream.
• Can I use this for propane applications? Provided the gas is in vapor form and non-corrosive, this regulator is fully compatible with LPG.
• What is the temperature rating for this unit? The standard operating range is -20°F to 150°F (-28.9°C to 65.5°C).
