ED. 2010/11
The adapter bracket can be supplied by
INOXPA as an accessory, although it may also
be made by the purchaser.
The bracket dimensions must be as indicated
on the figure shown here. The measurements
that are marked with an (*) may vary.
The screw sizes are for DIN 912 M5 allen
screws.

REPAIR / REPLACING OLD MODELS:
•
replacing INOXPA '94 head
. Order the
SCV1010
assembly kit (for actuators and butterfly/ball check valve) or kit
SCN1010
(for multi-way valves) along with the head.
•
replacing the Bürkert-model head
. Order the
SCV1011
assembly kit (for actuators and butterfly/ball check valve) or
kit
SCN1011
(for multi-way valves) along with the head.
The bracket/adapter must be fitted in such a way as to be properly aligned with the pneumatic
actuator rod.
Failure to observe this recommendation could result in the detectors failing to work correctly.
4.4.1.
Butterfly/ball valve with pneumatic drive. Figure 4.4
•
It is very important to keep the minimum distance (dimension figure A) for pneumatic drive butterfly valves in order to
enable the stripping of the actuator.
•
Should the head be fitted over another valve, it is extremely important to remember that enough space must be left in
order to be able to strip the valve for maintenance. The minimum recommended distance to enable the carrying-out of
head maintenance work would be dimension figure B.
4.4.2.
Multi-way valve. Figure 4.4
•
With respect to multi-way valves, cutoff valves must be distinguished from tank bottom valves.
•
In the event of installing the head over another valve, it is important to remember that enough space must be left in
order to be able to strip the valve for maintenance. The minimum recommended distance to enable the carrying-out of
head maintenance work would be dimension figure B.
