Richter products are known worldwide for their reliability and exemplary safety in complex plants, also under ex-
tremely difficult conditions, eg, with elevated temperatures and high solids contents or highly permeating media.
W
ith a complete range of plastic-
lined, shut-off, control and
safety valves, our products
are designed for use with difficult fluids,
regardless of whether they are corrosive,
hazardous, pure or even ultrapure. Many
years of experience enable us to also
control additional difficulties, such as high
and very low temperatures, solids con-
tamination or the risk of dry-running.
Richter is renowned for its solutions in
extremely demanding applications. The
chemical and pharmaceutical industries,
semi-conductor production, the petro-
chemical industry, the pulp industry, the
extractive metallurgy and metal process-
ing industries, food production, environ-
mental engineering, water desalination
and many other branches rely on the
extraordinary reliability and cost-effective-
ness of our products. Inside corrosion-re-
sistant plastics and engineered ceramics,
outside pressure-resistant metal housings
– Richter products prove to be problem
solvers in many fields of application, in
particular
• for fluids where stainless steels, iron
silicon alloy etc, and diverse plastics
are no longer sufficiently resistant to
corrosion,
• as alternatives to expensive special
metals and alloys, such as Hastelloy
®
,
titanium, Monel
®
and nickel,
• in large plants ('world scale plants'), eg,
chlor-alkali electrolysis and sulphuric
acid recycling plants,
• for applications with high demands on
the ease of cleaning of the wetted com-
ponents used,
• for pure and high-purity fine chemical
and semiconductor fluids high-purity,
• for highly permeating media,
• for media which must not come into
contact with metals, and
• when environmental protection regula-
tions demand the safe separation of
fluid and atmosphere.
Product effectiveness and advice on
applications go hand in hand; we there-
fore place great emphasis on staff and
customer training courses.
Valves and control equipment
The Richter product range of corrosion-
resistant shut-off, safety, sampling and
check valves, sight glasses, as well as
control equipment for control and shut-
off functions, is virtually complete.
These products are made to ISO/
DIN PN16/PN25 and ASME/ANSI 150
and 300 for temperatures from -60
to 200°C. They excel through robust
design and long service life.
The body is manufactured from
ductile cast iron EN-JS 1049/ ASTM
A395 or stainless steel, absorbing pres-
sure and pipework forces. Thickwalled,
vacuum-resistant linings – PFA, PTFE,
PFA-P (highly permeation-resistant) and
PFA-L (antistatic) – offer particularly
high resistance to corrosion.
Special pure media versions and a
comprehensive options package round
off the range. Certified series in compli-
ance with the German Clean Act and
with FDA are available.
• Shut-off ball valves, control valves,
PFA-lined, flange and sandwich
designs
• Shut-off and control butterfly valves,
PFA/PTFE-lined, sandwich, lug-style
and double-flange designs
• Bellows-sealed control and shut-off
valves.
Our quality ensures your safety
Plastic processing, mould and die
construction are performed in-house,
therefore direct influence can be
exerted particularly in the most impor-
tant phases in the manufacture of the
products. The design, production and
order processing procedures are laid
down in the ISO 9001/EN29001 quality
assurance system and they are audited
regularly and continuously refined.
Continuous investments in modern
production technology guarantee the
outstanding Richter quality. We deploy
Richter products are represented in
Southern Africa by Valve & Automation
(Pty) Ltd.
skilled workers in all production sectors
most of whom have been trained in-
house. Some 250 employees ensure that
your problems are solved in a reliable,
customer-orientated and cost-effective
way. Top quality is one of the standard
requirements which we not only place
on ourselves but also on our suppliers.
In this way we have been able to prove
ourselves worldwide as a reliable partner:
with solutions using innovative products
and a service on which you can rely.
Your requirements are our
yardstick
The continuous development of new cus-
tomer- and process-orientated solutions
characterizes the special value of our
work. Our innovations have established
themselves as trend-setting and state of
the art. Maintaining this position is a chal-
lenge which we confront anew every day.
Some examples of pioneering develop-
ments are:
• Globe control valves RSS with heavy-
duty bellows and a unique seat/plug
design for even the smallest kv/Cv
values
• Control valves KNR with a special
V-control ball and play-free torque
transmission
• Cavity-free sealless sampling valves PA
• Safety valves KSE, KSEA and LPV for
vapours, gases and fluids special chlor-
alkali electrolysis design.
