صمام التحويل في نظام التدفئة HS15 ProKondens

Heating bypass valve HS15 for ProKondens boiler is designed to automatically maintain the pressure differential in the system. It opens when the set pressure is exceeded, directing part of the coolant past the radiators, which protects the equipment from overloads. This part is especially important in systems with thermostatic valves when some circuits are closed. The HS15 valve ensures stable boiler operation and extends the service life of the circulation pump. When replacing the bypass valve, use the original spare part to maintain factory settings and reliability.
