4.1
Valve position indication (fig. 4.1)
For the valve position indication, a proximity switch holder (PSH)
can be installed direct on the actuator.
To signal the limit position of the valve seat, proximity switches can
be mounted to the holder if required.
We recommend our APV standard types:
operating distance: 5 mm / diameter: 11 mm.
If the user decides to apply valve position indicators other than
APV type, we cannot take over the liability for any malfunctions
resulting therefrom.
