D44, D4, D51, 18, 19 Directional Ball Valve

Worcester’s Series D51 is a standardized line of flanged diverter ball valves in sizes 2", 3", 4", 6", and 8" with ANSI Class 150 flanges. 

D51 diverter valves are designed to accept media through a bottom inlet port and direct it out either of two outlet ports. 

They are commonly used for alternately diverting flow from a single source to two different lines; for example, dumping operations in which one outlet permits media to flow from a common source to the process while the other outlet alternately dumps or recirculates excess media. 

Flowserve Worcester Controls’ Series 18 and 19 multi-way valves are designed to improve the efficiency and productivity of your process systems with up to 5 ports, slip-on flanges, multiple seat and body materials, standard or full port, and optional pneumatic and electric automation and anti-fugitive emission design. 

Screwed, socket weld and butt weld ends are available as are slip-on flanges (ANSI Class 150 or 300).
