Operation and Installation Allow enough gap to ensure the valve will slip easily between flanges. Center the flange gasket and valve. OPERATION: PREPARATION / MINOR REPAIR 1. The valve can be fitted with various operating devices such as lever handle, manual gear, pneumatic actuator or Electric Actuator. 2. By rotating the disc counter-clockwise to open or clockwise to close, the flow inside the pipeline can be regulated or shutoff - whichever is desired. Regular maintenance is not needed. Occasional adjustment of the stem packing may be required using the gland flange studs and bolts. It...

Operation and Installation DESIGN DETAILS The NIBCO® Sure Seal® High Performance Butterfly Valve is a double eccentric (double offset) design. This design minimizes torque and increases valve service life by decreasing seat to disc interference throughout the disc travel. Valves are available in wafer and lug design for ASME Class 150# (2”-30”) and Class 300# (2”-24”). The valve is bi-directional by design but has a recommended flow direction which is clearly marked on the valve body. WARNING: Failure to properly clean the piping before start up can result in damage to the disc or seat....
