Ductile Iron Open Stem Soft Seal Flange Gate Valve

The main body of this ductile iron rising stem soft seal flange gate valve is made of ductile iron. Ductile iron has excellent mechanical properties, high strength and good toughness. Compared with ordinary cast iron, it can better withstand the pressure fluctuations in the pipeline and the impact of the external environment, greatly improving the durability and reliability of the valve. The rising stem design is one of its significant features. During operation, the valve stem moves up and down with the rise and fall of the gate. This design allows the operator to intuitively observe the position of the valve stem and accurately judge the opening and closing status of the valve, which provides great convenience for daily operation and maintenance, especially for complex pipeline systems that require frequent monitoring of valve status.

At the same time, the ductile iron rising stem soft seal flange gate valve has a soft seal structure as the core advantage of the valve. It uses elastic soft materials such as rubber as sealing elements. When the valve is closed, the rubber sealing surface on the gate fits tightly with the valve seat, which can effectively make up for the minor defects and unevenness of the sealing surface and achieve excellent sealing effect. Even in low-pressure or extremely strict leakage requirements, it can reliably prevent medium leakage and ensure the normal operation and safety of the system.
