Itron-Actaris 762650 Yellow/Black Spring 1-2 PSI B42

The Itron-Actaris 762650 Yellow/Black Spring is a calibration part used inside gas regulator assemblies to define the outlet pressure range between 1 and 2 psi. It operates by providing controlled mechanical resistance against diaphragm movement, allowing the regulator to open or restrict gas passage at a preset pressure level. Fitted in B42 series gas regulators, burner assemblies, and HVAC systems used in gas-fired heating and combustion control equipment, it sets pressure response behavior for fuel delivery regulation, enabling accurate pressure modulation, stable burner ignition conditions, and controlled gas supply adjustment within heating circuits.
