Applications

General Description
The German - standard cast - iron globe valve is designed and manufactured in accordance with German national standards. It is a key type of valve widely used in various industrial applications, mainly used for cutting off fluid or regulating fluid flow. It features a simple structure, convenient operation, good sealing performance, and strong corrosion resistance.
Structural Components
Valve Body: Usually made of cast iron or ductile iron, which have good casting performance and machinability, and can adapt to different working conditions1.
Valve Cover: Also made of cast iron or ductile iron, which is closely connected to the valve body to form a sealed cavity.
Valve Stem: Made of bronze or stainless steel, which has good corrosion - resistance and anti - friction performance. The valve stem is used to drive the valve disc to move up and down, and its lifting position is usually indicated to make the operation more intuitive1.
Valve Disc: Usually made of ductile iron, which moves along the center line of the valve seat. By changing the position of the valve disc, the flow rate of the fluid can be adjusted and the on - off control can be realized1.
Sealing Forms
Soft Sealing: Soft sealing materials such as rubber and polytetrafluoroethylene are usually used as the sealing surface. This sealing form has good sealing performance, which can effectively prevent the leakage of the medium. However, its applicable temperature is relatively low, generally suitable for working conditions with a temperature not exceeding 150℃. It is applicable to occasions where the temperature requirement is not high and the medium is relatively pure and free of particles, such as the pipeline for transporting water and gas at normal temperature.
Hard Sealing: The sealing surface is made of metal materials such as stainless steel and cemented carbide. It has the advantages of high temperature and high - pressure resistance, and can maintain good sealing performance under high - temperature and high - pressure conditions. However, the processing accuracy requirement of hard sealing is relatively high to ensure the fit of the sealing surface. It is commonly used in high - temperature and high - pressure industrial pipeline systems, such as steam pipelines and petrochemical pipelines.
