KTM Dual-V High Performance Control Ball Valves
Series WA Sizes DN 25-200 Class 150 and 300
KTM
Enhanced, proven design offers both control and block
valve functions
Features
• Unique dual-V ball features a secondary
(Small) V-notch allowing extremely
small, accurate flow rates
• The primary (Large) V-notch
provides　straight through and nonclogging flow
• Dual-V ball allows rate changes and
controls fluids with a rangeability in
250:1
• Equal percent flow characteristic
• Rotary-valve design provides shearing
action between the V-notch ball and the
seat, promoting a smooth, non-clogging
operation
• Spring loaded stellited metal seat
• ANSI / FCI 70-2 Class V
• Unibody design protect from the effect
of piping stress
• Minimum body cavity reduces build-up
• Fugitive emissions control for flammable
and non-flammable applications
• Available in flangeless or flanged
construction
• Multiple, adjustable ring packing
allows easy adjustment without valve
disassembly or actuator removal
• ISO mounting pad is available as
optional
• Positive position indication
General applications
Slurry and viscous fluids, powder (option)
and pellet, sludge in water treatment and
pollution control processes, chips and fibers
in pulp and paper process, flow control in
pipeline and transmissions, pressure control
in oil and gas
Options
• Special tests
X-ray test (RT)
Liquid penetrant test (PT)
Positive material identification (PMI)

KTM Dual-V High Performance Control Ball Valves
Series WA Sizes DN 25-200 Class 150 and 300
Integral mounting pad
Fugitive emissions control packages
Machined ‘actuator pad’ allows precise
mounting of actuator. Mounting bolts are
independent from the shaft-packing gland
bolts. This exact alignment reduces torque
and prevents out-of-line wear on the shaft
and packing (option).
Available for both flammable and nonflammable service.
Shaft to disc connection
A tapered pin connection is used to ensure
accurate control of flow, which also results
in a high resolution of 250:1.
Positive locking, end cap retention
Wire-ring with three point locking device
assures tight fit and makes maintenance
easier.
Note: DN 15 to DN 100
valve illustrated
Versatile end-connection
The Unibody design is available in flangeless or flanged construction and meets ISA S-75.04 and ASME B16.10 (Short pattern) face-to-face
dimensions.
Minimum body cavity
Unique dual-V ball
Reduces build-up of transition process
materials and the segmented V-ball
eliminates freeze-up.
A secondary (Small) V-notch allows
extremely small, accurate flow rates with
the additional benefit of the primary (Large)
V-ball providing straight through, nonclogging flow which, if necessary, will
shear slurries and fibers.
Unibody design
This proven structural design enhances
piping integrity by reducing stress and
additionally eliminates potential leak paths.

Seat design
The precision finished heavy duty ‘V’ ball surface and spring supported, stellited metal seat
combination provides excellent sealing performance with low torque. It also offers the additional
benefit of exceptional wear and pressure drop performance over a wide range of media - steam,
gas, liquid, fiber and slurry applications.
