Ressort pour corps de dérivation ECOHEAT Gas / ProKondens, référence 433

Spring for bypass housing of ECOHEAT Gas and ProKondens boilers (position 433) provides the necessary force for the bypass mechanism operation. It returns the valve or damper to its original position after changes in pressure or temperature. The spring is made of spring steel, resistant to cyclic loads and corrosion. When replacing, it is important to select a spring with the correct stiffness and dimensions so that the bypass functions correctly. A worn spring can lead to unstable heating system operation, so it should be replaced if defects are found.
