Fenwal 22-100000-630 Ignitor Sensor this brass safety valve isThe Fenwal 22 100000 630 Ignitor Sensor is a high precision combustion component engineered for flame rectification in industrial and commercial gas fired systems. Designed to interface with direct spark ignition (DSI) modules, this sensor utilizes a glazed alumina ceramic insulator to maintain high dielectric strength and electrical integrity in environments reaching temperatures up to 2100F. As an essential part of the flame sensing circuit, it
