When reinstalling a manual valve, which bolts should you insert first?

When reinstalling a manual valve, it is essential to ensure proper alignment and sealing of the valve to prevent leaks and functional issues. In this case, inserting the bottom bolts first is the best practice because it helps to align the valve in a stable manner against the mounting surface.

By securing the bottom of the valve first, you provide a stable foundation that keeps the valve in position while you tighten the other bolts. This method also allows for easier adjustments if needed, as the bottom bolts can hold the valve in place while ensuring that the top section is leveled correctly before final tightening.

Securing the bottom first helps avoid misalignment that could occur if only top or side bolts were used initially. This practice ensures that pressure is evenly distributed and minimizes stress on the valve body, which could lead to damage or failure in sealing. Proper fastening order is vital to maintaining the integrity and functionality of the valve in the system.
