High operational safety

in pharma water
systems



GEMÜ 650 TL

GEMÜ has developed a diaphragm valve with a pneumatic
actuator and integrated handwheel for use in ring mains
which can, if necessary, be closed from a central control
system. Using the new GEMÜ 650 TL manual sampling can be
inhibited on a temporary basis.


In a pharmaceutical production process, it is necessary to sanitise
and maintain aseptic conditions throughout the storage and
distribution system of the pharma

water installation at regular
intervals during periods of production downtime. Due to the low
investment and operating costs involved, chemical sanitisation
using ozone and thermal sanitisation using hot water or steam are
the sanitisation measures most c
ommonly used in industrial
processes.

To be able to check the quality of ultra
-
pure water, it is necessary
to carry out regular checks at precisely defined measuring points in
the individual distributor loops. Pharmaceuticals standards require
that quality
-
related measurement variables such as bacteria count,
conductance and TOC* values be considered. This data is
acquired from samples taken in the return lines of each of the
individual distributor loops using sampling valves.

Diaphragm valve GEMÜ 650 TL

GEMÜ solution protects employees

In some cases, it can be necessary to keep sampling valves

closed in order to inhibit manual

sampling. This would, for example, be the case if the water temperature in the loop after hot water
sanitisation is so high that employees could scald themselves when taking samples. To prevent this,
the sampling valves can be kept closed via a central con
trol system and pilot valve until the water
temperature has dropped to a safe level again. Only then are employees able to take samples.

Another possible scenario is as follows: if too many tapping points are simultaneously open, the
pressure in the distri
butor loop will decrease and drop below a critical level. In this case, the master
control system could intervene and inhibit sampling in the same way. The valves would not be
released for manual operation until the pressure in the loop is again within an
acceptable range.


For such purposes, the GEMÜ 650 TL has a pneumatic actuator in addition to the integrated
handwheel. The valve can be closed automatically via a central control system and pilot valve


regardless of the position the handwheel is in. Thi
s increases operational and system reliability.

is one of the world’s leading manufacturers of valves, measurement and control systems. Since 1964, this globally
focused, independent family
-
owned enterprise has established itself in important industrial sectors thanks to its innovative
products and cus
tomised solutions for process media control.
GEMÜ

is the world market leader for sterile valve applications
in the pharmaceutical and biotechnology industries.

Today, the
GEMÜ
Group employs over 680 employees in Germany and more than 1,270 employees world
wide.
Manufacturing is carried out in six production companies in Germany, Switzerland, China, Brazil, France and the USA. From
Germany we coordinate global marketing with 20 subsidiaries. With a large distributor network in 53 markets, the GEMÜ
group is p
resent on all five continents.
GEMÜ

will continue to establish itself in future markets with its international growth
strategy. This will be achieved by the opening of a new Assembly and Logistics Centre in Germany in 2013, and in
Switzerland and China the
