Valve Casting Guide: Materials, Casting Processes, Defects, and Selection
Valve casting is an important manufacturing process for producing valve bodies, bonnets, covers, and other pressure-containing components. Compared with machining a valve body entirely from solid material, casting allows manufacturers to produce complex flow passages and large valve structures with ......

Gate Valves, Check Valves, and Globe Valves: How Do You Choose the Right Valve?
Gate Valves, Check Valves, and Globe Valves are widely used in industrial piping systems, but they are designed for different flow-control requirements. A gate valve is mainly used to isolate a pipeline, a check valve prevents reverse flow, while a globe valve is commonly selected for flow regulatio......

Why Does Heat Dissipation Matter in High Temperature Gate Valves?
When a gate valve is installed in a high-temperature pipeline, the valve body is not the only part exposed to heat. Heat from the process medium can travel through the valve body, bonnet, stem, and packing area. As the operating temperature increases, components that normally work without problems m......
