Range of application
AUMA spur gearboxes GSTI 25.1 – GSTI 40.1 are used for the operation of
valves (e.g. gate valves and globe valves).
They are qualified for use in nuclear power plants inside and outside
containment. They are designed for manual operation as well as motor oper-
ation in conjunction with electric actuators.
As the case may be, deviations from the qualified versions may exist for
these products. These deviations have been discussed and agreed between
customer and manufacturer (AUMA).
Deviating versions are stipulated in the order acknowledgement and may be
enquired from AUMA stating the commission number (refer to the name
plate). Before using the product, check whether the respective service
conditions match those of the version contractually stipulated in the order
acknowledgement.
For other applications, please consult AUMA. The manufacturer is not liable
for any possible damage resulting from use in other than the designated
applications. Such risk lies entirely with the user.
Observance of these operation instructions is considered as part of the
designated use.
