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, therefore

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,

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. 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)

to 24”.

This valve can be used with all types of

actuators and automat devices. Manual

Chains, Gearboxes, Pneumatic Actuators,
