4. Auxiliary Equipment
The valve can optionally be equipped with manual seat lift or seat lift
actuator.
Reconstruction can be undertaken during operation without greater
efforts.
-
Seat lift actuator
The SI2 valve can be equipped with a seat lift actuator if necessary
for reasons of cleanability and / or remote function control.
(see chapter 5)
-
Valve feedback
A proximity switch to signal the closed or open position of the
valve seat (ON/OFF) can be mounted on the seat lift actuator (C) if
required.
We recommend using one of our APV standard types.
Operating distance: 5 mm / diameter: 1 mm / length: 30 mm.
If the customer decides to use a valve feedback other than APV
type, we cannot take over any liability for a faultless function.
