Sensus 243-12-2F Regulator

The Sensus 243-12-2F is a robust industrial gas pressure regulator engineered for commercial and industrial applications where high capacity and precise pressure control are required. This model features a 2" flanged connection and a 3/4" orifice, optimized for handling significant flow rates while maintaining stability. Equipped with a green spring, this unit provides a specific outlet pressure range suitable for large-scale boiler feeds and commercial furnaces. The 243-12-2F is technically identical to the 243-12-1-2F, utilizing the same internal valve body and diaphragm assembly. Designed for ease of maintenance, the union nut connection allows for quick access to the orifice and valve seat without removing the entire body from the piping. This natural gas regulator excels in fixed-factor billing scenarios and is compatible with air, CO2, and propane, making it a versatile component for professional contractors managing diverse mechanical systems.

• High Flow Capacity: Large diaphragm area and 3/4" orifice support high-demand HVAC gas pressure regulation.
• Interchangeable Components: Simplifies field servicing with parts shared across the 243-12 series.
• Durable Construction: Heavy-duty cast iron body and flanged ports ensure leak-free performance in high-stress environments.
• Internal Relief Valve: Provides essential overpressure protection for downstream equipment.

Common Questions

What is the maximum inlet pressure for the Sensus 243-12-2F?
The maximum allowable inlet pressure depends on the specific orifice size and spring selection, but the 243-12 series is typically rated for up to 125 psi, though the 3/4" orifice is often used at lower pressures to maximize flow stability.

Can this regulator be used for propane service?
Yes, the Sensus 243-12-2F is compatible with LPG/Propane, as well as air, nitrogen, and carbon dioxide, provided the spring and orifice are sized correctly for the specific gravity of the gas.

Is the 243-12-2F suitable for indoor installations?
When installed indoors, the regulator vent must be piped to the atmosphere in accordance with local mechanical codes to ensure safety and proper industrial regulator performance.
