One of the primary factors contributing to the price of gate valves is the material used in their construction. Gate valves are typically made from various materials, such as cast iron, stainless steel, brass, and plastic. Each material varies in terms of durability, corrosion resistance, and temperature tolerance, leading to different price points. For instance, stainless steel gate valves are often more expensive than their cast iron counterparts due to their superior corrosion resistance and ability to withstand extreme temperatures. As such, project requirements—such as operating conditions and fluid characteristics—play a crucial role in determining the type of gate valve needed and, subsequently, its cost.
