3�1 Mount to valve/gear
If actuators are delivered mounted to a valve, this step has been done in the valve manufacturer’s
factory. However, the setting has to be checked during commissioning.
■
Heed safety information (refer to chapter 1.1)!
■
Prior to starting the assembly
– Make sure that the intended measures (possible operation of the valve, etc.) are not likely to
cause any injuries to persons or to interfere with the equipment.
– Heed the local ambient conditions, in particular the vibration load, which can be caused
when mounting an actuator to a vibrating valve
■
During assembly, the output shaft insert may fall out of the output drive shaft.
■
When disassembling the electronics cover, make sure the insert does not fall down.
It is recommended that the services and support of the responsible SIPOS Aktorik service centers
are utilized for all planning, installation, commissioning and service tasks.
3�1�1 General assembly instructions for all output shaft types
■
Mounting and operation is possible in any position. Heed the local ambient conditions, in particu-
lar the vibration load, which can be caused when mounting an actuator to a vibrating valve.
■
Do not apply force and avoid shocks!
■
Thoroughlycleanmountingfacesofoutputmountingangesatactuatorandvalve/gear.
■
Slightly grease the connection points.
■
Place the actuator on the valve/gear, making sure it is properly centered.
■
The bolts used upon delivery are not greased. Use bolts with at least 8.8 quality. If similar stain-
less steel bolts are used, they should be greased slightly using petroleum jelly.
The depth of engagement should be at least 1.25 x the thread diameter.
■
Position the actuator on the valve/gear and tighten the bolts evenly in diagonally opposite se-
quence.
■
The housing of the SIPOS SEVEN actuator consists of an aluminum alloy which is corrosion re-
sistant under normal environmental conditions. If the paint was damaged during assembly, it can
be touched up with original paint supplied in small quantity units by SIPOS Aktorik.
3�1�2 Output shaft type A
Assembly instruction
The stem nut is screwed onto the valve stem by turning the crank handle or the hand wheel.
Spring-loaded A end shafts are subject to high pre-tension. Fitting and removal of the stem nut for
thread cutting must be performed in accordance with assembly instructions!
Fitting and removing the stem nut
Ifthestemnutwasnotorderedwithatrapezoidalthread(sufx"Y18"toordernumber),orifthe
stem nut is worn and has to be replaced, proceed as follows:
Output ange (g., item 1) does not have to be removed from the rotary actuator!
