This bulletin covers the DN 25 through 600 (NPS 1
through 24) V150, V200 and V300 Vee-Ball control
valves. The Vee-Ball valve combines globe valve
ruggedness with the efficiency of a rotary valve. The
Vee-Ball valve is a segmented ball valve which features
a contoured segmented V-Notch ball. 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
V150, V200, and V300 valves mate with a variety of
ASME raised face flanges, as well as with EN 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
