M Series Arnett’s M Series Knife Gate Valve is
known as a LUG/Wafer, Semi-LUG or Narrow
Body Knife Valve. It has an easily recogniz-
able robust design and a thick knife, with
renewable sleeves made from carefully
studied high resistance material, there- fore
guaranteeing excellence in mining services.
Suitable for BIDIRECTIONAL operation,
symmetrical body, lightweight and minimum
space required for installation.
Suitable for working with abrasive and
corrosive fluids thanks to the wide range of
materials which the bodies, knives and
sleeves can be made from, whilst turbulence,
which can lead to premature wear inside the
valve and in the nearby pipe system, can be
eliminated with the shut-off valve. This
condition also ensures low load loss, thus
allowing optimal performance of the pumping
and conveyance systems.
For proper installation and operation, this
valve should be mounted between two
connection flanges which will compress the
sleeves or seals, thus creating a sealtight
fitting and allowing the knife to travel
smoothly in opening and closing. Its main
use is in line services and applications where
the piping can be depressurised and drained
in disassembly and maintenance. The Arnett
standard for M Series 2” to 24” (DN-50 to
DN-600) is 10 bars (150 PSI), making this
product one of the most robust and reliable in
this series.

X Series Arnett’s X Series Knife Gate Valve is
considered to be a High Performance Knife
Valve. Robustly designed with renewable
reinforced sleeves made from carefully
studied high-resistance material, therefore
guaranteeing maximal performance in mining
services. Bidirectional service and symmetri-
cal body.
Suitable for working with highly abrasive
fluids, whilst turbulence, which can lead to
premature wear inside the valve and in the
nearby pipe system, can be eliminated with
the shut-off valve. This condition also
ensures very low load loss, thus allowing
optimal performance of the pumping and
conveyance systems.
It’s most outstanding feature is the design
of the sleeves, which are permanently
adjusted through a compressor ring which
forms part of the connection flange. For this
reason, this valve is suitable for use as an
end-of-line in pressurised systems or
systems with load, and is ideal in work areas
where piping sections, hoses, movable pump
units and pools need to be assembled and
taken down for maintenance or operation.

H Series Arnett’s H Series Knife Gate Valve is
defined as a High Pressure LUG-Type Knife
Valve (20 bars or over). It has a robustly
designedbody for working at maximal
performance under high pressures, with
renewable sleeves made from carefully
studied high-resistance material, therefore
guaranteeing excellence in mining services.
Suitable for bidirectional operation,
symmetrical body, working pressures
available on request up to 52 bars (780 PSI).
Suitable for working with abrasive and
corrosive fluids thanks to the wide range of
materials which the bodies, knives and
sleeves can be made from, whilst turbulence,
which can lead to premature wear inside the
valve and in the nearby pipe system, can be
eliminated with the shut-off valve.
This condition also ensures low load loss,

smoothly in opening and closing. For specific
application in high pressure services which
require robust, well manufactured blocking
element. For application in conveying
solutions with a high con- centration of high
pressure solids such as slurry pipelines,
tailing pipelines, high pressure pulp pump
impulses, drainage in high pressure lines, etc.

Standard Components
T Series ARNETT’s T Series Knife Gate Valve is
built to comply with TAPPI Directives TIS
405-8 and MSSSP-81. Known as LUG-Type
Knife Valve. Its standard design corresponds
to a UNIDIRECTIONAL service valve,
although we can also prepare this unit for
BIDIRECTIONAL service. As with all our
products, CMO’s robust design is included
as standard.
Suitable for Industrial Water, Reclaimed
Water, Muddy Water, Industrial Liquid Waste
services and, in general, for all fluids
containing a solids load of up to 6%. It is an
ideal product for reliable use in water
distribution and sectorisation systems,
operation loops, run-offs, drains, etc. Its
design allows work within a maximum
pressure range of 150 PSI (10 bars)
