Proper installation of a wafer butterfly valve is essential to ensure reliable performance, long service life, and leak-free operation.
A wafer type butterfly valve is a compact, lightweight flow control device designed to fit between two flanges. Unlike lug-type valves, wafer valves rely on flange bolts passing through the valve body to maintain alignment and sealing.
✅Insert the valve between the pipe flanges, making sure the valve body is centered.
✅Align the flanges, checking that the valve disc can rotate freely without touching the pipe walls.
✅Insert and hand-tighten the bolts through both flanges and valve holes.
✅Gradually torque bolts in a star pattern to ensure even pressure on both sides.
✅Cycle the valve open and closed to ensure smooth operation and no obstruction.
✅Conduct a pressure test to check for leaks or irregularities in flow.
Whether you’re looking for an electric actuated wafer butterfly valve, a PVC butterfly valve for low-pressure systems, or a custom OEM butterfly valve design, our factory provides expert engineering support and flexible customization for your project needs.
