Tips: How to install a wafer ball valve?
To install a wafer ball valve, start by ensuring the pipeline is clean and free of debris. Position the valve between flanges, aligning the bolt holes. Place the gaskets on each side of the valve, ensuring a proper seal. Insert bolts through the holes and tighten them evenly to secure the valve in place. Check the alignment to avoid any misalignment issues. Once properly positioned, torque the bolts according to the manufacturer’s specifications. Verify that the valve operates smoothly and check for any leaks. Finally, conduct a pressure test to ensure the valve’s integrity.
