Product Description

The cast iron rising stem flange gate valve is made of ductile iron as the main material. Ductile iron has high strength, high toughness and good casting performance. It can withstand high pressure and harsh working environment, laying a solid foundation for the long-term reliable operation of the valve. The rising stem design is its remarkable feature. During operation, the valve stem will move up and down with the rise and fall of the gate. The operator can quickly and accurately judge the opening and closing state of the valve by visually observing the position of the valve stem, which greatly improves the convenience and safety of operation.

The valve is connected to the pipeline through flange connection or other standard connection methods. It is easy to install and disassemble. It can be widely used in water supply and drainage, HVAC, petrochemical, electric power, metallurgy and other fields.
