HoneywellQ335C1023-Thermoelement900 mm

Thermocouple Honeywell Q335C1023B (length 900 mm) — original safety thermoelectric flame sensor for gas equipment. Also known in warehouse inventory systems under part number 534.799.900. This element is a critical component of the gas boiler or water heater safety system: when heated by the pilot flame, the thermocouple generates voltage, keeping the electromagnetic valve open. If the flame goes out, the thermocouple cools, current stops, and the valve automatically shuts off gas, preventing leakage. Purpose and compatibility: Honeywell Q335C1023B thermocouple belongs to the Q335 series — quick dropout thermocouples designed for use with Q313 thermogenerators as part of pilot burners. It is typically used with Q382 pilot burner. Compatibility with gas boilers: This thermocouple is widely used in automation of gas boilers from Russian manufacturers. Experts note that Honeywell Q335C1023B can be installed instead of the standard thermocouple on boilers of the following brands: Manufacturer/Boiler type Specific models/Series ZhMZ (Zhukovsky Machine-Building Plant) AOGV, AKGV, KOV series "Comfort" and "Universal" Other brands Attack, Mora, Sime, Borodinskie, Rostovgazapparat Application Boilers with Honeywell automation (millivolt valves) Important: The length of 900 mm indicated in the product name is an extended version of the standard thermocouple (standard is 750 mm), convenient for boilers with remote gas valve location.
