Ductile iron gate valve with Bronze Seat DN1500 with by pass valve
The function of the bypass valve of the gate valve installed on the large water pump is to exhaust and add water:
1. When a large water pump starts to work, if there is air in the water pump, it will cause the pump to produce very harmful cavitation effects on the pump body and impeller, and it may even be impossible to get water;
2. In order to prevent the above problems, a bypass valve is installed. The bypass valve is mainly used to fill the water pump with water before the pump working, and at the same time, remove the air from the pump. When the water is filled to the part higher than the pump, the pump can start pumping and the pump can also work normally.
