A flexible wedge gate valve is designed with a wedge that can expand or contract in response to temperature changes, which helps prevent the valve from jamming. This design is particularly beneficial in systems where temperature fluctuations occur frequently, as it allows the valve to maintain a proper seal and functionality under varying conditions. The flexibility of the wedge allows it to accommodate thermal expansion of the valve material, ensuring that the valve operates efficiently without getting stuck.

The flexibility feature also enables it to better align with the valve seat, providing a strong seal and minimizing leakage. This is important for maintaining the integrity of the system where the valve is installed, regardless of the temperature variations it might experience.

While the other options touch on specific conditions or limitations, they do not encompass the broader application of flexible wedge gate valves, which can indeed be useful in various scenarios, not limited just to high-pressure or liquid applications.
