High operational safety

in pharma water


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

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.

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.
