    What is the cast steel gate valve?

    The cast steel gate valve is a commonly used valve. The valve consists of a valve body, gate, and seal. The opening and closing direction of the gate is perpendicular to the fluid. The cast steel gate valve is easy to install, the structure is compact, and the seal is reliable. It is widely used in oil, natural gas, chemical industry, steel, cement and other industries. Its main characteristics are easy to open and close operation, wear resistance, corrosion resistance, long service life. It can adapt to a working environment with high temperature and high pressure or low temperature and low pressure.

    What is a stainless steel gate valve?

    Stainless steel gate valve is a kind of valve made of stainless steel as the main material. It has the advantages of stainless corrosion, corrosion resistance, high temperature resistance, low temperature resistance, etc. It is widely used in chemical, petroleum, natural gas, medicine and other fields. Stainless steel gate valves usually adopt flat plate gate valve structure design. It has the advantages of top bolts, adjustable screws, and anti -static electricity. It can adapt to different industrial applications. In addition, the stainless steel gate valve also has the advantages of good sealing performance, small opening and closing torque, flexible operation and so on, which can meet the requirements of specific industrial production.

    The cast steel gate valve is an important type of valve, and its main advantages are as follows:

    1. High-intensity and reliable sealing

    The wedge disc and seat of the cast steel gate valve are made of cast steel materials, which can withstand greater pressure and temperature changes. In addition, the sealing structure is adopted between the wedge disc and the seat. The advantage is that the sealing performance is good and reliable, which can completely cut off the flow body to prevent leakage.

    2. High corrosion resistance

    The cast steel gate valve is made of cast steel. It has good corrosion resistance and abrasion resistance, which can adapt to complex and variable process liquids, and is suitable for a variety of medium acid and base media.

    3. Long service life

    The material of cast steel gate valves have high hardness, strong wear resistance and long service life.

    4. A wide range of applications

    The cast steel gate valves can be used in various fields, such as chemical, petroleum, natural gas, power, urban water supply and other fields. It can not only be used in the environment of normal temperature and normal pressure, but also is widely used in special operating conditions of high temperature, low temperature, high pressure and low pressure.

    The stainless steel gate valve is a high-performance, durable valve, and its main advantages are as follows:

    1. Corrosion resistance

    The biggest feature of stainless steel is that it has strong corrosion resistance, can tolerate the erosion of various chemical media and acid-base substances, and can be used in a harsh working environment.

    2. Excellent high temperature resistance

    The material of stainless steel has excellent high temperature resistance, and it can still maintain good performance at high temperatures, which can adapt to industrial applications in high temperature and high pressure environments.

    3. Long life and low maintenance costs

    Stainless steel has good corrosion resistance and abrasion resistance, can be used for a long time without frequent maintenance and replacement, reducing production costs.

    The difference between the cast steel gate valve and the stainless steel gate valve are mainly reflected in the following aspects:

    1. Different materials

    The cast steel gate valve is mainly made of carbon steel, alloy steel, stainless steel and other metal materials, while the stainless steel gate valve is made of stainless steel material.

    2. Different corrosion resistance

    The main feature of the stainless steel gate valve is corrosion resistance, while the corrosion performance of the cast steel gate valve is poor.

    3. Different structure and service life

    The structure of the cast steel gate valve is simple, the service life is relatively short, the structure of the stainless steel gate valve is relatively complicated, the manufacturing process requirements are high, and the service life is relatively long.

    4. Different applicable environment

    Due to the stainless steel gate valve has excellent corrosion resistance and high temperature resistance, it is suitable for special working environments such as chemical industry, petroleum, and medicine. The cast steel gate valve is mainly used in ordinary industrial production and construction projects.
