Worcester Controls Three Piece Ball Valves Series 44, Series 45, Series 59

Series 44 Ball Valves A quantum advance in ball valve durability, cycle life, leak tightness and automation. Flowserve Worcester Controls Series 44 three-piece ball valves, for many years the most respected ball valve design in the industry, are now better than ever. A major research, design, and testing program brings you a new valve, designed to ANSI B16.34 specifications with advanced seal technology and body mount bracket design. This means a very strong, tough valve that can handle pressure and unforeseen piping strains with a stem seal that extends operational cycle life and a...

The range of Worcester Controls’ seat materials is unmatched and includes Buna, Neoprene, TFE, Reinforced TFE, Polyfill, Lubetal™, High-per Fill and UHMWPE. Body-Mounted Actuator Design Actuators for Worcester Controls Series 44 three-piece valves are mounted on rigid, precisely machined, box-style brackets bolted to the valve center section. This brings a number of advantages to the valve user: • Actuator loads are on the valve body; • Actuators and brackets can be removed for service without affecting valve or piping integrity; • Easy access for stem seal adjustment; • Inventory...

Swing-Out Design For Easy Maintenance Special Service and Approvals Underwriter Laboratory Listed Flammable liquid shutoff (YRBX) Gas shutoff (YRPV) LP gas shutoff (YSDT) The Series 44 is especially well suited for use in piping systems where line breaks are required and total entry into the line is necessary. The center section can swing out, eliminating the need to cut a valve out of line and having to replace both the valve and the pipe. Because of this design, the seats, seals and ball can all be replaced quickly and easily without disturbing pipe alignment. Acting as both a valve and a...

Operating Torque for Automated Valves • Maximum Temperature for Seals: UHMWPE: Valve Torque: Graphite coated Stainless Steel: Before the actuator can be sized for any given valve application, the operating torque required for the valve must be determined. The operating torque of the ball valve is influenced by a number of factors—some are design- and materials-related, others are application- (service conditions) related. Design-related factors include the type and material of the valve seats, while application factors include system pressure, media and frequency of operation. TFE coated...

Series 45 Ball Valve Compact, Large Diameter, Three-piece Ball Valves Substantially Reduced Installation and Maintenance Costs For OEM equipment and packaged piping systems, Worcester Controls Series 45 ball valves provide the best performance for the least installed cost in the 21/2"–6" size range. Flanges are an integral part of the valve design, providing savings in flanges, nuts, bolts and labor. Threepiece construction also means that the valve functions as both valve and union. This is a valuable feature in welded piping systems where line breaks are required. Easily Automated for...

Series 59 Full-Port Ball Valves 1/4"–2" Series 59 valves are rated to ANSI Class 600. 3" and 4" valves are rated to ANSI Class 300. Manual and automated valves for processes requiring maximum flow area Full-port ball valves are recommended for processes requiring minimum restriction through piping, shutoff valves, and other equipment. For example, pump inlet valves are often full-port valves. Full-port valves are also useful in systems handling slurries, viscous fluids and fluids with residues, and where the capacity to pig lines is desired. Flowserve Worcester Controls offers a complete...
