Sensus 243-12-IRV-2 Regulator

The Sensus 243-12-IRV-2 Regulator is a heavy-duty, large-capacity gas pressure regulator engineered for commercial and industrial gas distribution. This specific configuration features a 2" NPT cast iron body paired with a 3/4" orifice, providing the high-flow performance required for boilers, furnaces, and large-scale combustion equipment. Equipped with the Green Spring, this unit delivers a precise outlet pressure range of 6" to 14" w.c., making it a reliable choice for natural gas pressure regulator applications where stable downstream pressure is critical.

Built for technical versatility, the 243-12-IRV-2 includes an Internal Relief Valve (IRV) to enhance system safety by providing over-pressurization protection. The 4-bolt union connection allows for 360-degree diaphragm rotation, simplifying installation in tight piping configurations. This industrial gas regulator is designed for a maximum inlet pressure of up to 125 psi (depending on orifice selection and safety limits) and excels in high-demand environments like schools, hospitals, and manufacturing plants. Its interchangeable orifice and spring design ensure long-term field adaptability for various commercial gas regulator needs.

• Internal Relief Valve (IRV): Provides integrated over-pressurization protection to shield downstream equipment.
• High Flow Capacity: The 2" NPT connection and 3/4" orifice handle significant loads for industrial gas services.
• Precision Control: The green spring ensures stable 6-14" w.c. delivery, ideal for fixed-factor billing and pressure-compensated metering.
• Field Versatility: Features a 360-degree union for flexible mounting in any orientation and easy valve inspection.
• Rugged Construction: Durable cast iron body and aluminum diaphragm case withstand harsh professional environments.

• Can this regulator be used for Propane? Yes, the 243 series is compatible with natural gas, LPG vapor, air, nitrogen, and other inert gases.
• What size is the vent connection? This model typically features a 1" NPT screened vent to ensure proper breathing and relief capacity.
• Is this suitable for underground use? No, the Sensus 243-12-IRV is not recommended for buried service applications.
