Safety instructions and measures
NOTICE
!
Risk of regulator damage due to excessively high or low tightening torques.
Observe the specified torques when tightening regulator components. Excessive tighten
-
ing torques lead to parts wearing out more quickly. Parts that are too loose may cause
leakage.
Î
Observe the tightening torques specified in section 7.3.
Risk of regulator damage due to the use of unsuitable sealants or lubricants.
The sealants and lubricants to be used depend on the regulator material. Unsuitable
sealants and lubricants may corrode and damage surfaces.
Î
Only use sealants and lubricants approved by SAMSON (see section 7.3).
Incorrect control due to the formation of ice on the regulator.
Medium temperatures below 0 °C may cause ice to form on the regulator, depending
on the air humidity. This may affect, in particular, the functioning of the actuator stem
guide of the Type 2373 Regulator.
Î
Prevent the formation of ice by taking appropriate precautions (e.g. enclosure, trace
heater etc.). The plant operator is responsible for selecting and implementing appro-
priate precautions.
Regulator damage due to condensed glycol.
In principle, the materials are also resistant to high concentrations of glycol. Neverthe-
less, glycol reacts when it comes into contact with metals and causes acids to form. We
cannot prevent this reaction.
Î
Use suitable inhibitors. The plant operator is responsible for the selection and use of
suitable inhibitors.
Risk of regulator damage due to incorrectly attached slings.
Î
Do not attach load-bearing slings to the actuator housing.
Risk of excess pressure damaging plant sections due to construction-related seat leak-
age through the regulator.
Î
Always install a safety device (e.g. safety excess pressure valve or safety relief valve)
in the plant.
