What is the required torque setting range for securing a pressure/vacuum vent valve according to Executive Order VR-201-A?

• A. 10-20 ft. lbs.
• B. 20-50 ft. lbs.
• C. 50-75 ft. lbs.
• D. 75-100 ft. lbs.

Answer: (B)

The required torque setting range for securing a pressure/vacuum vent valve, as specified by Executive Order VR-201-A, is indeed 20-50 ft. lbs. This torque range is critical to ensure that the valve is secured adequately without risking damage to the components or compromising the integrity of the vapor recovery system. Proper torque settings help to maintain a seal that prevents leaks and ensures the system operates efficiently, effectively managing vapor release during the loading and unloading of fuels. This is especially important for safety and environmental concerns regarding vapor emissions. Using a torque setting outside this specified range could lead to operational issues or potential failures of the valve system, highlighting the importance of adhering strictly to prescribed guidelines.
