▶ The installation must not cause back pressure to build up.
▶ Selectahosewithsucientcrosssectionfortheconnection.
▶ Design the exhaust air line in such a way that no water or other liquid can get into the device
through the exhaust air port.
▶ The pressure supply must always be at least 0.5–1 bar above the pressure required to bring the
actuator into its end position.
→ Connect the control medium to the pilot air port (1)
(3–7 bar, instrument air, oil-free, anhydrous and dust-free).
→Connect the exhaust air line or a silencer to the exhaust air port (3).
