9.3.1 Replacing the seat and
plug
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.
Risk of damage to the facing of the seat and
plug due to incorrect service or repair.
Always replace both the seat and plug.
The socket wrench for DN 15 to 25 can also
be made, for example from a GEDORE
screwdriver bit (IN 19-19) by drilling a
17-mm-deep hole (Ø17) into a 17 mm hex
bit.
