Sensus 243-8-HP-2 Regulator

The Sensus 243-8-HP-2 Regulator is a robust, large-capacity industrial gas pressure regulator designed specifically for commercial and high-pressure distribution work. This 2-inch NPT gas regulator features a heavy-duty cast iron body and a high-accuracy diaphragm assembly, making it the standard for commercial boiler gas pressure regulation and industrial furnace applications. This specific configuration utilizes a 1-inch orifice and a cadmium spring, professionally calibrated for an outlet pressure range of 3 to 6.5 PSIG.

Engineered for technical precision, the Sensus 243-8-HP-2 delivers stable natural gas flow control even under fluctuating inlet conditions. The union connection design allows for 360-degree diaphragm rotation, simplifying tight-space mechanical room retrofits. While optimized for natural gas service, this unit is fully compatible with LPG vapor, air, nitrogen, and other inert gases. This high-pressure service regulator prioritizes positive dead-end lockup and consistent regulation for large-scale combustion equipment and master meter sets.

• Large Capacity Output: Designed to handle high-volume demands for factories, foundries, and large commercial boiler systems.
• Field Versatility: The 4-bolt union connection enables fast inspection and allows the diaphragm to be serviced without removing the body from the line.
• Precise Pressure Control: High-performance spring and 1-inch orifice combination ensures minimal droop and maximum accuracy for fixed-factor billing applications.
• Durable Construction: Features an ASTM A126 Class B cast iron body and a reinforced Buna-N diaphragm for long-term reliability in demanding environments.

Common Questions:

What is the maximum inlet pressure for the Sensus 243-8-HP-2?
With the 1-inch orifice installed, this high-pressure model typically supports a maximum inlet pressure of 25 PSIG. Always consult the capacity tables to ensure the inlet pressure does not exceed the recommended limits for your specific flow requirements.

Does this model include an internal relief valve (IRV)?
No, the 243-8-HP series is a high-pressure specialty regulator and does not come equipped with an internal relief valve. For applications requiring overpressure protection, an external relief valve must be installed downstream.

Can I install this regulator in a vertical piping run?
Yes, the 243-8-HP can be installed in any orientation. However, to prevent moisture and debris accumulation, the 1-inch NPT vent should be positioned to point downward or be piped to a safe atmospheric discharge location.
