Honeywell SV9502H2522 Smart Gas Valve – 24V Intermittent Pilot / Hot Surface Ignition, Upgraded OEM Furnace Control

Condition: New

The Honeywell SV9502H2522 is a factory-new, upgraded version of the SmartValve™ Series designed for use in gas-fired appliances requiring intermittent pilot or hot surface ignition. Operating on a 24V control system, this valve combines both electronic ignition control and gas flow regulation into a compact, intelligent module. Widely used in residential furnaces and commercial HVAC units, this SmartValve provides precise gas flow control while ensuring safe startup sequences and proper burner operation.

With its integrated automation, it eliminates the need for separate ignition modules and simplifies installation and diagnostics. It supports both intermittent pilot and direct hot surface ignition systems, making it a universal replacement for various older Honeywell models.
