resilient wedge vs solid wedge gate valve

  • Gate Valve Types, Construction, Applications and Advantages

    Split wedge or flexible wedge type gate valves are expected to perform better than solid wedge gate valves when thermal binding is a concern. Pressure Binding Sometimes in high temperature applications, the flow medium, such as water or steam, is trapped in the valve bonnet area when the valve is closed for system shutdown.
