How to Install a Butterfly Valves.

• Clean the pipeline of all contaminants.
• Determine the direction of the fluid, torque as flow into the disc may generate higher torque than flow into the shaft side of the disc
• Position disk in the closed position during installation to prevent damage of disc sealing edge
• If possible, at all times the valve should be mounted with the stem in horizontal to avoid pipeline debris collecting at the bottom and for higher temperature installations
• It should always be installed concentrically between flanges as mentioned above. This helps to avoid damage on the disc and eliminates interference with the pipeline and flange
• Use an extension between the butterfly valve and wafer check valve
• Try the disc by moving it from the closed position to open and back to ensure it moves flexibly
• Tighten the flange bolts (tightening in sequence) to secure the valve following the manufacturers recommended torques

THESE VALVES REQUIRE FLANGE GASKETS ON BOTH SIDES OF THE VALVE FACE,  SELECTED FOR THE SERVICE INTENDED

*Comply with all the safety and good industry practice.
