Update On Maxseal - Perrelet Associates Content Solutions

Integrity - a tradition spanning half a century
For decades, the Maxseal name has been associated with process management in
many of the most exacting environments in the world. Today, from the North Sea to
South-East Asia, through North Africa, South America and the Middle East,
Maxseal solenoid valves have a proven track record of safety and reliability. Since
the 1950s, when the original concept was developed for nuclear power applications,
the scope has extended to industries as diverse as aerospace, defense,
power generation, mining and, of course, offshore and petrochemicals.
Safe, reliable and cost-effective Thompson
Valves solutions
Thompson Valves Ltd is internationally renowned for the high
technical added value of strong, dedicated brands such as
Maxseal solenoid valves and IVP pressure regulators.
Whether part of a packaged
solution or as individual components,
they have become standard
specification in a variety of
critical control and instrumentation
applications. This specialist
nature of the company's core
business means that Thompson
Valves is ideally positioned to
support customers with a level
of performance that is fine-tuned
to specific expectations.
Explaining a recent restructing,
in which three distinct business
units were created, Thompson
Valves Sales Director for
Industrial Products, Darren
Sheppard, commented that it
had resulted in clear
identification of market-led
opportunities for all areas of
the business.
Industry standard evolved from
an original concept
Maxseal was founded in 1952, by a group of engineers, to
manufacture reliable solenoid-operated valves for the
automation and control of process media. 1954 saw the
first of an ongoing series of developments that were to
continue throughout the UK nuclear-power build programme,
with units for the Calder Hall experimental
nuclear reactor. Read full story inside

Due to launch September 2005,
the new Maxseal IC03S solenoid
valve is a compact 2 kg version
of the market-leading IC04S,
featuring fully 316 stainless-steel
enclosure and valve construction
to IP66/X8.
The dual-certified, direct lift
solenoid design is magnetically
fine-tuned to operate a 1/4"
valve at 2.9W. Retaining the
traditional Maxseal generous
operating forces and safety
margins required for reliable
operation under the most
arduous conditions, the ICO3 is
typically suited to applications
such as emergency shut down
systems (ESD).
See inside for more details.

UK nuclear-power build programme, with units for t
By 1958, Maxseal was already
forging associations with larger
organisations such as Ruston
Gas Turbines (European Gas
Turbines, now Siemens), ICI and
The National Coal Board,
designing for instance valves for
the first automatic colliery at
Beavercoats.
The original, and now famous,
ICO4 - a 1/4" three-port direct
acting solenoid valve for instrument
changeover duties - was
developed for ICI in 1964.
Evolution models included twoport
and five-port configurations.
What was to emerge as the
worldwide market leader in its
class, offers the offshore and
petrochemical industries of today
a uniquely reliable and heavyduty
unit. A number of variations
on this proven design, such as
the ICO4N, ICO4P, ICO4D
(4.5W) or ICO4S (stainless steel),
cater for a range of specific
applications.
Joint development work with
the Ministry of Defence began in
earnest in 1965. This produced
an entire, purpose-built, new
range of solenoid and servooperated
valves. Options from
1/4" to 6" were fitted to Royal
Navy and other naval craft
around the world, both conventional
and nuclear.
Over the period 1978-80,
Maxseal was working on a 1/4"
three-port pilot-operated intrinsically
safe solenoid valve to ICI

ment of the product range was
eventually launched as the ICO2,
to which a CSA version was
added later.
During the 1980s flameproof
certificates were updated from
Health and Safety, Buxton, to
BASEEFA and CENELEC
standards. The new certification
meant that solenoids up to
150W could be used in hazardous
areas requiring EEx e
and EEx d, as well as CSA
approved equipment.
Steady progress
In 1984, this inventive company
was purchased by the Bath and
Portland group (operating as a
division of KDG Instruments Ltd).
It became known as KDG
Maxseal Ltd, only to be taken
over by Meggitt plc in 1988, and
revert to the name Maxseal Ltd.
Then, in September 1994,
Maxseal was acquired by
Charles Baynes plc (subsequently
the FCX group; Truflo
International since August 2005)
and relocated from Bristol to the
Thompson Valves factory in
Poole, Dorset.
While these events were taking
place, Maxseal was steadily progressing
on other fronts too,
with BS 5750 registration in
1991 and ISO 9001 in 1994.
It was in 2001 that Maxseal
decided to pursue new opportunities
in the low ambient temperature
market, proceeding to
In June 2005, the Maxseal team was strengthened by the
technical expertise and enthusiasm of new Sales Manager
Scott Waugh. Scott will focus on development opportunities
in Europe and the Middle East. Describing the commitment
of the Maxseal team, Sales Director Darren Sheppard
added: “Exciting market opportunities mean that this
world-renowned product and its potential are hugely
important to Thompson Valves”.
