Choosing and fitting
When selecting a replacement spring of this type, verify that the pressure range and marking color match the original component, as these indicate the intended setpoint. Ensure the spring is correctly seated in its guide or cap to avoid misalignment, which can cause unstable pressure or erratic switching. Inspect the spring for distortion, cracks, or loss of temper before installation.
Signs of failure
Failure of such springs typically manifests as pressure fluctuations or unstable regulation in the gas system. The equipment may exhibit erratic switching or inconsistent outlet pressure. Check the spring for physical damage, deformation, or signs of fatigue, and replace it if any issues are found.
