Frequently Asked Questions
For which products will kits be
available?
Clarkson Tiered Spare Parts Kits will
initially be available for Model KGD and
KGA+ Knife Gate Valves in sizes NPS 2 - 24
(DN 50 - 600).
Can I still buy individual components?
Components that are part of a kit will only
be available for purchase as a complete
kit. Non-kitted critical components
are available; please contact your local
Emerson representative for support
options.
Can I still buy spare parts with special
materials?
Special material sleeves and gates are still
available for purchase separately.
What if I do not need all parts of the kit?
Emerson recommends changing all
tiered kit parts at the same time as good
maintenance practice. Many of the
components interact, wear at the same
rates, and will impact the service life of
other parts.
Will prices change?
No. Kit list prices are equal to the sum of
their included components’ current prices
and any existing discount agreements will
be honoured.

Clarkson™ Tiered Spare Parts Kits
Why OEM Quality Matters
Your choice of Knife Gate Valve replacement parts can be the difference between a productive, protable
process, and a decommissioned unit. Don’t risk the safety of your people, your equipment or the
environment with inferior imitation parts – when you can get the right parts, right now.
Achieve extended valve life with optimized sleeve durometer
that allows sufcient elastomer memory for ideal compression
on the gate while ensuring 100% man-safe, positive isolation.
Run your processes for longer with sleeves supported by a fully
encapsulated stiffener ring that resists heavy shearing forces
during actuation, while remaining protected from corrosion.
Rest assured of the highest quality every time you see the
Clarkson name. Each sleeve is rigorously tested by our elastomer
experts to ensure identical, industry-leading performance.
Bank on longer performance with patented compound
formulations that maximize resistance to compression-set, tear,
wear, rolling, bursting and chemical attack.
Tiered Spare Parts Kits
Emerson’s Clarkson Spare Parts Kits are tiered to improve valve
service life while optimizing your spare parts inventory. Kits are
tiered in order of expected frequency of use and should cover
the vast majority of your standard maintenance requirements.
Clarkson kits are composed of parts that should always be fully
consumed, as one component’s condition will affect the wear
and service life of other components.
