Sensus 121-8-HP-2 Regulator

The Sensus 121-8-HP-2 Regulator is a high-capacity, commercial gas pressure regulator designed for demanding industrial combustion and distribution applications. Featuring a 2" NPT cast iron body and a high-pressure spring configuration, this unit is engineered to deliver a precise 3-6.5 PSIG outlet pressure range. As a veteran-grade high-pressure gas regulator, it provides the fast speed of response necessary for boilers, furnaces, and large-scale gas engines where maintaining stable manifold pressure is critical. Its external sensing capabilities and roll-type diaphragm ensure accurate pressure regulation and positive dead-end lockup, even when subjected to high inlet pressures up to 60 PSIG.

This industrial gas regulator is fully compatible with natural gas, propane (LPG), air, and nitrogen. The rugged die-cast aluminum alloy diaphragm case and cadmium-plated springs provide the durability required for technical HVACR environments. Contractors prioritize the 121-8-HP series for its large capacity throughput and the simplicity of its field-replaceable orifices, making it a staple for primary control and monitoring stations.

• Exceptional Flow Stability: Specifically designed for fast-response industrial burners and air heaters.
• Rugged Construction: Cast iron body and non-corrosive diaphragm case withstand harsh mechanical room conditions.
• High Inlet Capability: Safely handles maximum inlet pressures of 60 PSIG while maintaining setpoint accuracy.
• Versatile Media Compatibility: Suitable for natural gas, propane, nitrogen, and other non-corrosive gases.
• Precise Dead-End Lockup: Soft seat design ensures tight shutoff during zero-flow conditions.

• What is the maximum inlet pressure for the Sensus 121-8-HP-2? The unit supports a maximum inlet of 60 PSIG with a standard 3-6.5 PSIG outlet spring.
• Can this regulator be used for propane service? Yes, this 2 inch gas regulator is compatible with LPG/propane using standard correction factors for capacity.
• Does this model require an external control line? Yes, the 121-8-HP series utilizes external sensing for superior regulation accuracy downstream.
