A44/459 Series – Three Piece Reduced Ball Valve

The Flowserve Worcester Controls three-piece reduced ball valve delivers rugged, high-performance reliability for a range of applications, all in an easy-to-maintain design. A variety of pipe ends, including socket weld, screwed or butt weld ends enables these valves to be adapted to fit both standard and more unusual piping specifications while the range of seat materials handles steam, chemicals, cryogenic gases, petroleum products, caustics, abrasive materials or fluids containing solids.

As you would expect, Worcester has developed and improved the Series 44/459 over the years to maintain its position as the 8-150mm valve design which others strive to equal. The 59 and 599 series full bore versions complete the range of 3-piece valves.
