5. Auxiliary Equipment
5.1. Valve position indication
Proximity switches to signal the limit positions of the valve shafts
can be installed at the main cylinder if required (fig. 5.1.)
D1 = valve position "closed"
D2 = valve position "open" (only for DN 40 - 50, 1,5” - 2”)
D3 = valve position "open" (only for DN 65 - 150, 2,5” - 6”)
We recommend to use our APV standard types:
operating distance: 5 mm / diameter: 11 mm
If the customer decides to use valve position indicators other than
APV type, we cannot take over any liability for a faultless function.
