and pneumatically operated housings

Preparation of the equipment

The housings are mounted and fixed on the vessel (reactor, tank,
pipe, etc.) by means of a ring nut in conjunction with a weld-in
socket, by a flange connection or a 1" MNPT external (male)
thread.
Attachment of the weld-in socket or the flange connection to the
vessel is the responsibility of the customer.
Note: Weld-in sockets with thread G 11/4" (internal ø= 25 mm,
L= 40 mm, straight or at an angle of 15°) are available from
your supplier in a choice of materials.
Important! After welding, the bore of the weld-in socket must be
checked and reamed to size 25-H7 if necessary.
To ensure correct functioning of the retractable housing, please
note the following information on positioning:
