While optimized for horizontal runs

this motor offers the exact technical parameters required to maintain system airflow and static pressure requirements without compromising the integrity of the original equipment design

which means it will close the circuit once the system pressure rises above the cut-in threshold

Technical Reliability: Features a 2-second on-delay to prevent nuisance trips and a robust construction rated for 1/2 HP and 3/4 HP motor applications

Lubricate the O-ring with compatible refrigeration oil and tighten the assembly to the manufacturer's torque specification to prevent pinching or extrusion under pressure

Lochinvar & A.O. Smith 100276814 Relief Valve R-410A While optimized for horizontal runsThe Lochinvar & A. O. Smith 100276814 Relief Valve is a critical safety component designed for high demand commercial and residential water heating systems. This 1" 150# T&P Relief Valve is engineered to automatically discharge water if internal tank conditions exceed 150 PSI or 210F, preventing catastrophic vessel failure. As a direct replacement for 100167360, this OEM part ensures precise fitment and maintains the original engineering
