The Johnson Controls VG1241BL is a heavy-duty 3/4 inch NPT ball valve engineered for precise proportional control in commercial HVAC systems

the assembly should be used within a NEMA-rated enclosure if the TF actuator and linkage are exposed to direct weather or extreme moisture

Rheem-Ruud 62-23554-82 DSI Module R-410A though it is professional practiceThe Rheem Ruud 62 23554 82 is a mission critical 24V Direct Spark Ignition (DSI) control module designed for precise burner sequencing in high efficiency gas furnaces and commercial heating equipment. Engineered as a direct replacement for the 62 23554 02, this integrated furnace control manages the ignition cycle with a rigorous 30 second prepurge and a 7 second trial for ignition (TFI) window. Its microprocessor based logic ensures consistent flame
