Lochinvar & A.O. Smith 100337748 High/Low Gas Pressure Switch

Lochinvar & A.O. Smith 100337748 Gas Pressure Switch is a safety part used in gas-fired heating systems. Its main function is to regulate pressure of the gas inside the system in an efficient way so as to prevent occurrence of incidents. This component Used two distinct pressure sensors: One of them is intended to search for high pressures while the other is intended to search for low pressures. In cases where pressure of the gaseous fuel increases, which is a real possibility, the high pressure sensor turns off the system to prevent cases of explosions and other mishaps. On the other hand if the pressure is low than minimum required pressure for combustion, the low pressure sensor initiates the shutdown system.
