this is an automatic pilot safety valve designed specifically for standing pilot applications where a thermocouple is used to monitor the pilot flame

Smith burner assemblies

As a Plenum Rated component meeting NFPA 90A and UL 1820 standards

the 031-00808-000 prevents arc-over at the switching contacts and shields sensitive solid-state relays and PLC output modules from premature failure and electromagnetic interference (EMI)

the 78H40 and 78H4001 are functionally and physically identical

Carrier LH680003 Pilot Assembly 322838-753 this is an automatic pilotThe Carrier LH680003 Pilot Assembly is a critical OEM replacement component designed for high reliability intermittent pilot ignition in specific Carrier, Bryant, and Payne gas fired furnaces and water heaters. As a veteran grade three wire pilot assembly, this unit integrates both the ignition source and the flame sensing mechanism required to prove the pilot flame before the main burner gas valve is authorized to open. In these legacy systems, the
