Installation
The shaft ends of the ball valves / flap valves can be adjusted to the supplied star shape size with reducing
sleeves which can be purchased separately.
The order numbers and an overview of the available reducing sleeves can be found in the chapter entitled
“13. Accessories”.
Further information is available from your Bürkert sales office.
Important information for continuous function:
Do not attach rotary actuator head first!
Otherwise the medium may run out of the fitting into the actuator.
The required installation height of the rotary actuator above the ball valve / flap valve can be found in the
chapter entitled Dimensions. Specify an additional distance of 100 mm.
Installation procedure:
Figure 7: Standard installation
→
Ensure that the ball valve / the flap valve is in its closed position.

When connecting the rotary actuator, ensure that it is not twisted and that the fastening threads of the rotary
actuator are covered by the fastening bores of the ball valve / flap valve.
