Gate Valve Thermal Binding in High-Temperature Steam Service: Causes, Prevention and Wedge Selection
Case Study: Preventing Thermal Binding and Unseating Failure in a Steam Isolation Gate Valve Gate valves used for high-temperature steam isolation are expected to provide reliable shutoff and operate when needed, even after exposure to significant temperature changes. In practice, however, thermal expansion can affect the relationship between the valve body, wedge, seats, and other
