Description

Kromschroder Spring 03089130 is a calibration spring used in gas pressure regulators or gas valves within gas-fired burners and boilers. It is identified by manufacturer code 03089130 and article number 624.625.053. The spring is color-coded black and light-green, and it is specified for a pressure range of 12.5–25 mbar. It operates by exerting force on a diaphragm; adjusting its compression sets the outlet or differential pressure.

Further details

Color coding notes	colour coding helps identify the range during service
Compatibility note	no compatibility with specific burner or boiler models is claimed here
Replacement recommendation	compare the existing spring's markings and dimensions with the codes given
Selection criteria	key parameters are the pressure range and the physical dimensions: length, outer diameter, and wire thickness
Spring function	used inside gas pressure regulators or gas valves to set the outlet pressure or the differential pressure across the valve
Verification	refer to the valve manufacturer's documentation to confirm the correct pressure range and spring part number

Choosing and fitting

When selecting a replacement spring of this type, verify that the pressure range and physical dimensions (length, outer diameter, wire thickness) match the valve's spring housing. The color code serves as a cross-reference but must be confirmed against the pressure range and valve type (direct-acting or pilot-operated). Compare markings and dimensions with the existing spring or consult the valve manufacturer's documentation if the old spring is missing.

Signs of failure

A spring with an incorrect pressure range can cause improper burner output or unstable flame, potentially leading to lockout or unsafe combustion. Symptoms may include fluctuating gas pressure, burner ignition failure, or erratic flame behavior. Check the spring's markings and dimensions against the valve specifications if such issues occur.
