This bulletin covers the NPS 1 through 2, NPS 3 through 12 Series B, and theNPS 14 through 20 V150, V200 and V300 Vee-Ball control valves. The Vee-Ball valve combines globe valve ruggedness with the efficiency of a rotary valve. A shearing action between the V-notch ball and the ball seal (figure 1) promotes smooth, nonclogging operation. The unrestricted straight-through flow design provides high capacity for gas, steam, liquids, and fibrous slurries.
V150, V200, and V300 valves mate with a variety of ASME raised face flanges, as well as with DIN flanges (see Specifications). To meet specific application requirements, a variety of
metal and soft ball seal materials are available. A splined drive shaft combines with a variety of power
operated and manual actuators to provide reliable, high-performance throttling or on-off operation for
many different applications in the process industries. Unless otherwise noted, all NACE references are to NACE MR0175-2002.
Valve Sizes and End Connection Styles
V150: NPSJ 1,J 1-1/2,J 2,J 3,J 4,J 6,J 8,J 10,J 12, flanged valves that mate with CL150
raised-face flanges (see table 1). Also, NPS 3 through 12 mate with PN classes (see table 1)
