Structural characteristics of concealed cast iron gate valve:

1. The structure is simple and compact, the design is reasonable and innovative, the rigidity of the valve is very good, the channel flow area is large, the medium is unobstructed, and the resistance is small;

2. The sealing surface is made of hard alloy and stainless steel, which have reliable sealing performance and long service life;

3. The cast iron concealed stem gate valve is filled with graphite material for easy operation;

4. Multiple driving methods can be used, such as manual, electric, pneumatic, gear transmission, etc;

5. The positions on both sides of the gate valve channel are symmetrical to each other, so the medium can flow freely to both sides, making installation very convenient;

6. The structural length of cast iron concealed stem gate valves is short, and the manufacturing process used is good, with a very wide range of applications;

Summary of concealed cast iron gate valves:

1. Cast iron concealed stem gate valves are mainly used for connecting and cutting off media in pipelines. The opening and closing component of the valve is a gate, and the direction of movement of the gate is perpendicular to the flow direction of the medium. Cast iron concealed stem gate valves are mainly made of ductile iron, which is very lightweight, only about 20% to 30% of traditional gate valves;

2. Cast iron concealed stem gate valve is a product belonging to the gate valve series, and it is also a replacement for traditional gate valves. By compensating for the slight deformation caused by the gate plate, the valve achieves good sealing effect. Cast iron concealed stem gate valves have the advantages of convenient opening and closing, reliable sealing, good elastic memory, and long service life. They can be widely used as regulating and shut-off devices in pipeline systems such as metallurgy, sewage, electricity, medicine, construction, food, textiles, tap water, and energy.
