7.4 Replacing the operating
diaphragm
Risk of regulator damage due to excessively
high or low tightening torques.
Observe the specied torques on tightening
regulator components. Excessively tightened
torques lead to parts wearing out quicker.
Parts that are too loose may cause leakage.
Observe the specied tightening torques.
SAMSON's After-sales Service department
can support you concerning lubricant,
tightening torques and tools approved by
SAMSON.
The associated order number is written on
the actual operating diaphragm.
