The advantages of cast steel gate valves are low fluid resistance, and the sealing surface is less susceptible to medium brushing and erosion. Opening and closing are more effortless. The flow direction of the medium is unrestricted, does not disturb flow, and does not reduce pressure. The structure is simple, the length of the structure 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.
