صمام التحويل G 3/4 بوصة لـ GWT

The G 3/4" bypass valve for GWT is designed to maintain a constant flow of heat transfer fluid in the small circulation loop, preventing boiler boiling when thermostatic valves are closed. It is installed in the bypass line and automatically opens when the pressure differential exceeds a set point, ensuring safe boiler operation. The valve with G 3/4 thread is suitable for most domestic and semi-industrial boilers. When replacing, it is important to select a valve with similar characteristics in terms of actuation pressure and connection type. A properly functioning bypass valve extends the service life of the heat exchanger and pump, preventing water hammer and overheating.
