A tamper valve must signal receipt within how many turns of the hand wheel?

1. One turn

2. Two turns

3. Three turns

4. Four turns

The correct answer is: Two turns

The correct response highlights the requirement that a tamper valve should signal receipt within two turns of the hand wheel. This specification is critical for ensuring that the valve operates efficiently and safely. In practical terms, when a tamper valve is turned, it is essential for the valve to reach a clear indication of its position or activation within a relatively short range of motion. The two-turn limit helps to minimize unnecessary effort and time spent adjusting the valve, allowing for quicker responses in situations like emergency shutdowns or maintenance checks. This specification also reinforces consistency in valve operation, as operators who are familiar with the two-turn signal can quickly identify whether the valve is functioning properly or if adjustments are needed. The requirement aligns with industry standards and best practices for safety and usability in plumbing systems, further emphasizing its importance in practical applications within the field.
