▶ When rotating the actuator, ensure that the valve is in open
position.
Procedure:
→ Clamp the valve body in a holding device
(applies only to valves which have not yet been installed).
→ Control function A pressurize the pilot air port 1 with com-
pressed air (5 bar): valve opens.
→ Counter on the flats of the nipple with a suitable open-end
wrench.
→ Place suitable open-end wrench on the hexagon of the
