Kromschroder Spring 03089121

The Kromschroder Spring 03089121 is a spare part for gas pressure regulators, specifically designed for the GDJ 20 and GDJ 25 series. It operates within a pressure range of 5–15 mbar and is marked with dark green and light blue colors. The spring is made of spring steel and is suitable for use with natural gas, LPG, biogas, and air. It is certified to EN 88-1 and has a maximum operating pressure of 400 mbar. This spring ensures high adjustment accuracy, contributing to stable and precise gas pressure regulation.

When selecting a replacement spring of this type, ensure that the pressure range and physical dimensions (diameter, free length, wire thickness) match the original component. The color coding indicates the pressure range, so verify it corresponds to the required setting. Installation is straightforward: remove the old spring and insert the new one, ensuring it is not deformed or fatigued. Always confirm compatibility with the specific regulator model before ordering.

Over time, springs of this kind can become deformed or fatigued, leading to inaccurate pressure regulation. Symptoms include unstable burner operation, pressure fluctuations, or failure to maintain the set point. If the equipment exhibits these issues, inspect the spring for signs of wear or deformation and replace it if necessary.
