Kromschroder Spring, white 75441810

The Kromschroder Spring, white 75441810 is a spare part for Kromschroder VSBV 25 and VSBV 40 safety relief valves, as well as VSVB 25 and VSVB 40 models. It operates within a pressure range of 320–500 mbar and is made of spring steel. The white color coding indicates its specific pressure range. This spring provides overpressure protection and allows for quick replacement without replacing the entire valve.

Parts of this type are selected by matching the required pressure range and color coding to the specific valve model. Before ordering, verify the valve model and the pressure range needed. During installation, note the original spring's adjustment setting and ensure correct orientation, as recalibration may be required after replacement.

When springs of this kind fail, the valve may not maintain the correct pressure, leading to overpressure or underpressure conditions. Symptoms include unstable gas pressure, valve leakage, or failure to open or close at the set point. Check the spring for deformation, breakage, or loss of tension, and compare its color coding and range to the valve specifications.
