Valvola di bypass per il riscaldamento HS25/S30

Heating bypass valve for models HS25 and S30 is designed to automatically regulate the pressure differential in the heating system. It activates when the pressure rises above normal, diverting part of the coolant to the return line. This prevents noise, water hammer, and excessive load on the pump. The HS25/S30 valve is an important component of the hydraulic group and is suitable for the corresponding boilers. If the bypass malfunctions, pressure fluctuations and unstable heating operation may occur. Installing the original part guarantees correct system operation.
