Essentially Varibell® consists of 3 functional units:
Seat - Control Bell - Cover Flange
These parts are merely plugged and can be replaced within a few minutes. Nothing has to be adjusted during or after assembly - everything adjusts itself. Actuator and positioner remain in place.
In multifunctional facilities the control bell can be exchanged against another with a completely different KV range within a few minutes.
