What is the minimum amount of time that a control valve can be closed?

• A. 3 seconds
• B. 10 seconds
• C. 5 seconds
• D. 7 seconds

Answer: (C)

The minimum amount of time that a control valve can be closed is articulated as 5 seconds. This duration ensures proper operation and functionality within the system. Closing a control valve too quickly can disrupt the flow dynamics and cause issues such as water hammer, which could lead to structural damage in the piping system or affect the performance of connected fire protection systems. The specification of 5 seconds as the minimum time allows for the controlled drainage of water or fluid, minimizing shock and allowing the system to remain stable. This is especially important in fire suppression systems, where maintaining pressure and flow is critical for effective operation. Understanding this timing is crucial for safety and operational integrity, reinforcing the importance of adhering to this standard in all installation and maintenance practices within the sprinkler fitting field.
