Trim Interchangeability - Across the Vee-Ball line,
size-for-size, trim components remain the same
regardless of body style. This reduces parts inventory
requirements and costs. It also simplifies maintenance
training and procedures.
Better Linkage Protection - Integral mounting of
positioner protects linkages.

Available in ceramic
and R30006 cobalt
alloy (Alloy 6), as well
as chromium plated
CG8M SST materials,
Micro-Notch balls
allow extremely small
flow rates.
Rotary attenuator
reduces liquid
cavitation and
aerodynamic noise.
Superior Bearings - To enhance the performance
and service life of the valve, a patented, low-friction,
high-load bearing system fully supports both drive
and follower shafts. To reduce maintenance costs, this
bearing system is designed to easily drop into place.
Characterized V-Notch Ball Design - The V-notch
ball provides positive shearing action for fibrous
flows and creates an inherently equal percentage
flow characteristic. It has been specially contoured to
maximize capacity and enhance seal life and shutoff
integrity. The Vee-Ball valve offers high capacity with
its unrestricted, straight-through flow path. The result
is accurate throttling control over a wide range of
flow conditions.
