M M Series BFII BUTTERFLY VALVES CONFORMING TO AWWA C504 Replaceable Seated 24-Inch and Greater Butterfly Valve Publication 504-106 Issue 06/12
Design Features General All AWWA Butterfly Valves are of the rubber-sealed tight-closing type designed to meet the latest AWWA C504 standards. All valves are cast from the correct material for line type in a thickness that exceeds the strength requirements for the associated valve classes. Flow-Thru Disc Valves are equipped with a disc that has been specially designed to flow the maximum capacity with minimal head loss. Extensive analysis and testing has been undertaken to assure that significant improvements in the valve coefficient could be achieved. The superior design of the Flow-Thru disc leaves a fraction of the surface area exposed to direct line flow compared with the traditional bowl shaped disc. Seat/Seal Detal Countinuously Adjustable Seal AWWA Butterfly Valves 24-inch and larger are equipped with a replaceable resilient seal. The seal material is customizable to the user s specifications and of an uninterrupted design to assure drip tight sealing. The seal is held in place on the body with a segmented ring and hardware made of corrosion resistant material. The seal is continuously adjustable throughout the perimeter of the valve line to assure smooth operation throughout the life of the valve. The seal can be replaced with the valve in line using only standard tooling and requiring no special training. A permanent electro-deposit welded seat is installed on the valve disc to provide maintenancefree operation for the life of the seal. Standard material is Stainless Steel 316, please inquire about additional options including Stellite and Nickel. 2 42-inch After Simulated Service Testing
Design Features Secured Shafts Standardized Bonnet All sizes are equipped with shafts that are mechanically secured to the disc. Positive positioning and indication is guaranteed by zero slip. Sealed Bushings While many manufacturers will allow the lineflow to contact bushings and bearings has chosen to isolate these components. Sealing rings have been placed between line-flow and all friction reducing and drive support components. This design feature allows a wider range of material options, increased service life, and reduces leakage possibilities. Unlike the majority of American valve manufacturers, supplies valves with standardized bonnet mounts unless otherwise specified. The use of International Organization of Standardization (ISO) or Manufacturers Standard Society (MSS) mount dimensions allows for the attachment of standardized gearboxes and operators without the need for specialized adapters. Eliminating these adapters often reduces cost, minimizes overall dimensions of the valve package, and reduces weight. Should there be a need to exchange or retrofit a newer operator this standardization expands options while reducing cost. The additional use of standardized stem diameters and key widths allows the direct mounting of many commercially available operators without any drive bush machining or adapter fabrication.

Design Features Simple Packing Replacement Design Standards AWWA C504 valves use a standard ISO valve stem size. This combined with industry standard stack heights allows for the use of off-the-shelf packing. The packing gland and retention design further allows for the replacement of the packing without removing the valve from the line. In most cases the line pressure can be maintained. All service can be performed without any special training.
