Key Benefits Precise Flame Pattern: Engineered port geometry ensures stable gas burner combustion and eliminates uneven heating across the heat exchanger

Using a valve undersized for the compressor's mass flow will cause excessive pressure drop

This Johnson Controls duct sensor is a passive

this spring provides the necessary linear feedback for stable medium-pressure steam or water flow regulation

any attempt to alter the setpoints will compromise the component

Robertshaw 780-783 Ignition Module 30067439-890 Key Benefits Precise Flame Pattern:The Robertshaw 780 783 is a critical HSI ignition module engineered for high demand gas fired heating systems and commercial cooking applications. As a direct replacement for the HS78034PL308A, this unit utilizes standard 120V AC supply voltage and 24V AC control voltage to provide reliable hot surface ignition. Designed for versatile field application, it supports both local and remote flame sensing, ensuring a stable flame rectification signal
