Wing Valve Exercise

Scenario:

A well experiences a sudden surge in pressure, causing the flow rate to exceed safe limits. The well operator needs to quickly reduce the flow rate to prevent potential damage.

Task:

1. Identify the appropriate action to be taken using a wing valve in this scenario.
2. Explain how the wing valve would be used to achieve the desired outcome.
