Servicing
Tip
Usually, this is the largest V‑shaped port.
2. On mounting the actuator, make sure
that the V‑shaped port uncovered first
faces toward the valve outlet.
NOTICE
!
Medium flow obstructed due to incorrect in‑
stallation of the V‑port plug.
To achieve the best flow conditions inside the
valve, the V‑port plug must always be in‑
stalled with the largest port facing toward
the valve outlet.
Make sure the V‑port plug is installed cor‑
rectly.
