What is the minimum clearance, in inches, required between any part of the cabinet and the valve handle after the valve is positioned from fully open to close?

• A. 1 inch
• B. 3 inches
• C. 2 inches
• D. 4 inches

Answer: (C)

The main idea is to provide enough space for the valve handle to sweep from fully open to fully closed without hitting the cabinet. When you turn the valve, the handle moves in an arc, so if the cabinet is too close, the handle can contact it at some point in the travel. For typical sprinkler system valves with standard handles, about two inches of clearance is the minimum to accommodate that full sweep safely. A smaller gap could cause interference, while a larger gap isn’t usually necessary as the minimum.
