9.3.2 Replacing the operating
diaphragm
Risk of regulator damage due to excessively
high or low tightening torques.
Observe the specified torques on tightening
regulator components. Excessively tightened
torques lead to parts wearing out quicker.
Parts that are too loose may cause leakage.
Observe the specified tightening torques.
SAMSON's After-sales Service can support
you concerning lubricant, tightening torques
and tools approved by SAMSON.
The stem surface is roller-burnished. Do not
reface the stem.
After replacing the diaphragm stem, the
nipple (guide bushing) in the actuator case
must be replaced as well.
The associated order number is written on
the actual rolling diaphragm.
