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. The operator should **partially close** the wing valve. 2. By partially closing the wing valve, the operator **reduces the flow area** through the valve, effectively **throttling the flow rate** and bringing it back within safe limits. This action helps to control the surge in pressure and prevent potential damage to the wellhead equipment or surrounding infrastructure.
