Pneumatic Connection - Burkert 2063 Series Operating Instructions Manual

→ Pressurise pilot air port 2 with compressed air (value as indi-
cated on the type label).
→ Actuate the diaphragm valve twice to position the diaphragm
correctly.
→ With applying pressure, tighten the body screws in three
stages (approx. 1/3, approx. 2/3, 3/3 of the full tightening
torque, according to "Tab. 10"), in each case tightening them
cross-wise. The diaphragm should be positioned and pressed
evenly all around the actuator and body.

Risk of injury from unsuitable connection hoses.
▶ Use only hoses which are authorized for the indicated pressure
▶ Observe the data sheet specifications from the hose
For control function I: Risk of pilot pressure failure.
The valve stays in an undefined position in the event of a pilot
