Advantages and disadvantages

1. The advantages of Cast Steel Gate Valves are: low fluid resistance, and the sealing surface is less susceptible to brushing and erosion by the medium. Opening and closing is more effortless. The flow direction of the medium is unrestricted, without disturbance or pressure reduction. The structure is simple, the structure length is short, the manufacturing process is good, and there are many materials available for high temperature and high pressure resistance, with a wide range of applications.

2. The disadvantage of Cast Steel Gate Valves is that they are prone to erosion and abrasion between the sealing surfaces, making maintenance difficult. The external dimensions are large, requiring a certain amount of space for opening and a long opening and closing time.
