Rotary Control Valves
Shaft Packing Options - A choice of shaft packing
systems (see ) provides enhanced shaft sealing to
meet specific application requirements.
Structural Integrity - One-piece body (see )
improves structural integrity of the pressure
boundary by eliminating the potential leak paths
found in two-piece, bolted valve designs.
Accurate Positioning - Splined driveshaft (see )
coupled with clamped actuator lever helps ensure
zero lost motion.
Process Compatibility - A wide choice of materials
for valve body, V-notch ball, ball seals, shafts, and
other components allows you to specify a Vee-Ball
valve to meet most process applications.
Standard body materials include both CG8M
(317) and CF3M (316L) stainless steel as well as
WCC carbon steel materials. Additional body
materials include CK3MCuN superaustenitic SST, and
nickel alloys CN7M (Alloy 20), M35-2 (Alloy 400) and
CW2M (Alloy C).

packing, which is available
in all Vee-Ball valves, helps meet
stringent emission control requirements.

Erosive Slurry Control - The V150S Slurry
Vee-Ball valve (see ) has a body liner, V-notch ball,
and flow ring all constructed of high-chromium iron.
A ceramic flow ring insert is available for especially
aggressive slurry services.
Medium Consistency Pulping - The V150E expanded
outlet Vee-Ball valve (see ) accommodates expanded
downstream piping.

V150S erosion-resistant trim
components protect the body from
erosive wear and are retained
without the use of press fits or
threads for easy replacement.

The V150E outlet flange is one
standard line size diameter larger
than the inlet. The expanded outlet
geometry streamlines the flow
through the valve as the flow
area increases from inlet to outlet.
