Normally, the control valve is delivered with
positioner and leakage sensor already
mounted.
If the leakage sensor is mounted after the
valve has been installed or it is mounted on-
to another control valve, proceed as de-
scribed in following.
NOTICE
Risk of malfunction due to incorrect
fastening!
Fasten the leakage sensor using a
torque of 20 ±5 Nm.

The M8 threaded connection on the NAMUR
rib should preferably be used to mount the
sensor (Fig. 19).
Tip:
If the positioner was mounted directly
onto the actuator (integral attach-
ment), the NAMUR interfaces on ei-
ther side of the valve yoke can be
used to mount the leakage sensor.
The start-up of the leakage sensor is de-
scribed in detail in the Operating Instructions
