Sensus 243-RPC-B-2F Regulator

The Sensus 243-RPC-B-2F Regulator is a high-performance, pilot-operated gas regulator designed for specialized commercial and industrial applications like pressure factor measurement and fixed-factor billing. Featuring a 2" flanged connection and a large 1" orifice, this unit utilizes a relay-principle operation to deliver exceptionally stable outlet pressure, maintaining ±0.5% accuracy even during significant inlet pressure fluctuations. The "B" designation indicates a throat opening construction paired with an internal control line, effectively eliminating the need for external downstream piping connections while ensuring a faster response speed to sudden load changes. Built with a rugged cast iron body, it safely handles natural gas, LPG vapor, air, and other non-corrosive gases across a temperature range of -20°F to 150°F. For maximum performance, ensure a minimum differential of 1.5 psi between the inlet pressure and the desired setpoint. This regulator is engineered for positive dead-end lockup, making it a reliable solution for boiler sets and industrial burner systems.

• Internal Control Line: Simplifies installation and reduces potential leak points by eliminating the requirement for an external downstream sensing line.
• Pilot-Operated Precision: Employs a relay-loading principle to maintain highly accurate pressure regulation within ±0.5% of absolute pressure.
• Rapid Response: The integrated throat opening allows the regulator to react quickly to the snap-acting demands of modern burners and boilers.
• High Capacity Flow: The 1" 30-degree orifice supports high-volume gas distribution for large-scale commercial facilities.
• Versatile Media Compatibility: Suitable for a wide range of inert gases, including nitrogen and dry CO2, in addition to standard fuel gases.

What is the maximum inlet pressure for this 1" orifice model?
With the 1" orifice installed, the maximum allowable inlet pressure for the 243-RPC-B-2F is 60 psi.

Does this regulator require an external control line?
No. The RPC-B model features an internal control mechanism; however, always verify your specific system requirements as some monitor setups may differ.

Can I adjust the pressure via the main regulator cap?
No. All outlet pressure adjustments must be performed through the pilot regulator. The main cover cap is a pressure-loaded vessel and should never be removed during operation.
