INSTALLATION & OPERATION GUIDE

Ensure sufficient space for valves for easy installation, operation, maintenance and replacement.
Verify the valves are suitable for the operating condition such as medium, operating pressure / temperature, etc.
Check the I.D. of the flange and pipe to ensure free disc movement.
Valves shall be mounted on flanges only after the counter flanges have been welded to pipe and cooled down tot he atmospheric temperature. Welding heat may damage the rubber seat of the valves. Never weld the flanges with valves installed. No gasket is required for installation of rubber seated butterfly valves.
Position the valves carefully between flanges. Accurate centering between flanges is essential to prevent any damages and problems during operation.
Valves should be installed by placing bolts through the hole and tightening carefully, ensuring even contact between the flange and seat.Too tight of space may cause damages to the seat and should be avoided.
Cross tighten all the bolts diagonally to distribute the loads evenly over the valves.
Turning the valves to ensure sufficient disc clearance.
Valves equipped with manual operators must be operated manually. Excessive external force on the operation of valve may damage the valve and / or operator.
Blind flange with short pipe should be used for dead end installation.
