1. The flow resistance is small, and the internal structure of the valve body is straight through, so the medium can be unobstructed;
2. The movement direction of the gate valve of cast iron rising stem gate valve is perpendicular to the flow direction of medium, and the opening and closing speed is fast and labor-saving;
3. The channels on both sides of the gate valve are symmetrical to each other, and the medium can flow freely to both sides, so it is easy to install the cast iron rising stem gate valve;
4. It has the advantages of simple structure, short structure length, good manufacturing industry, and can be used in various fields;
5. Made of ductile iron, the valve body is very light, only about 20% ~ 30% of the traditional gate valve;
6. Compact structure, good rigidity of valve, smooth channel, unique material of sealing surface, reliable sealing performance and long service life.
