Sensus 243-8-HP-1 1/2 Regulator

The Sensus 243-8-HP-1 1/2 Regulator is a high-capacity, heavy-duty industrial gas regulator engineered for precise pressure reduction in commercial and distribution applications. This high-pressure model features a 1.5-inch NPT pipe size and a robust cast iron body designed to handle rigorous flow requirements. Equipped with a 3/4-inch orifice and a cadmium spring, this unit provides a stable outlet pressure range of 3 to 6.5 PSI. The union connection between the body and the diaphragm case ensures rapid field servicing and versatility across various piping arrangements. This specific configuration is often utilized for fixed-factor billing and pressure-compensated metering where accuracy is paramount. Compatible with natural gas, LP vapor, and various inert gases, it is a reliable choice for boilers, large furnaces, and industrial kilns requiring consistent high-pressure gas regulation.

• Precision Control: The 3/4-inch orifice and high-pressure spring ensure consistent delivery for large-scale equipment.
• Superior Durability: Cast iron construction and a die-cast aluminum diaphragm case provide long-term resilience in industrial environments.
• Maintenance Efficiency: The 4-bolt union connection allows for quick inspection and orifice changes without removing the body from the line.
• Media Versatility: Suitable for natural gas, propane vapor, air, nitrogen, and dry CO2 applications.

Common Questions

What is the maximum inlet pressure for the Sensus 243-8-HP with a 3/4" orifice?
For this specific configuration, the maximum inlet pressure is typically rated up to 125 PSIG, though local codes and specific safety factors may dictate lower operating limits.

Can this regulator be used for internal relief?
The 243-8-HP is a high-pressure model. Internal relief valves (IRV) are generally not available in the HP (High Pressure) versions of the Sensus 243 series; secondary overpressure protection should be installed if required.

Is this regulator suitable for buried service?
No, the Sensus 243 series is designed for above-ground installation and is not recommended for buried applications.
