Sensus 243-8-2 Regulator

For large-scale commercial and industrial gas distribution, the Sensus 243-8-2 Regulator is a technician-preferred solution for over-pressurization protection and high-capacity flow control. This specific model features a 2-inch NPT connection and is configured with a 1/2-inch orifice, making it ideal for high-demand equipment like industrial boilers, furnaces, and large-scale water heaters. The 243-8-2 is functionally identical to the 243-8-1-2, providing contractors with flexibility in regional part numbering without sacrificing performance. Utilizing a 2-4.25 lb spring, this regulator maintains exceptional accuracy in pressure factor measurement and fixed-factor billing applications. The integrated Internal Relief Valve (IRV) enhances safety by providing a reliable path for excess gas discharge in the event of seat failure. Designed with a cast iron body and a union connection, the assembly allows for 360-degree diaphragm rotation, ensuring the service regulator can be installed even in tight mechanical rooms or complex piping configurations. Whether you are managing natural gas or LPG vapor, this unit provides the positive lock-up and dead-end performance required for modern combustion systems.

• Internal Relief Valve (IRV): Provides integrated over-pressure protection, eliminating the need for some secondary piping and external relief lines in specific configurations.
• Field Versatility: The 4-bolt union connection allows the diaphragm case to be rotated 360 degrees for convenient vent positioning during installation.
• High Capacity Design: Optimized for industrial burners and commercial laundries requiring consistent outlet pressure regulation at high flow rates.
• Durable Construction: Features a rugged cast iron body and a precision-machined 1/2-inch brass orifice for long-term reliability in demanding environments.
• Precise Control: Equipped with a 2-4.25# spring (black) ensuring stable performance for precision-metered gas services.

Common Questions

Is the Sensus 243-8-2 compatible with propane?
Yes, while commonly used for natural gas, this regulator is fully compatible with LPG vapor, air, dry CO2, and nitrogen applications.

Can I install this regulator in a vertical orientation?
Yes, the 243-8-2 can be installed in any position, including vertical or diagonal piping, provided the flow direction matches the arrow on the body and the vent is adequately protected from debris.

What is the difference between the 243-8-2 and the 243-8-1-2?
There is no functional difference; the models are identical in specifications, orifice size, and spring range.
