Servicing
Risk of valve damage due to excessively high
or low tightening torques.
Observe the specied torques on tightening
control valve components. Excessively tight-
ened torques lead to parts wearing out
quicker. Parts that are too loose may cause
leakage.
Observe the specied tightening torques
(uAB0100).
Risk of valve damage due to the use of un-
suitable tools.
Only use tools approved by SAMSON
(uAB0100).
Risk of valve damage due to the use of un-
suitable lubricants.
Only use lubricants approved by SAMSON
(uAB0100).
The control valve was checked by SAMSON
before it left the factory.
− Certain test results (seat leakage and leak
test) certied by SAMSON lose their
validity when the valve body or actuator
housing is opened.
− The product warranty becomes void if ser-
vicing or repair work not described in
these instructions is performed without pri-
or agreement by SAMSON's After-sales
Service department.
− Only use original spare parts by
SAMSON, which comply with the original
specications.
The procedure to remove or mount the actu-
ator for service work depends on the type of
attachment (FormB or FormC, see sec-
tion3.2).
