Installation of the valve
May be installed in any position, but preferably with the drive unit above.
Observe the flow direction (general rule for control valves: flow input under seat!)
Clean the piping of contamination!
Before connecting the valve housing, take care that piping is aligned!
In the case of weld-on housings, be sure to remove the drive unit before welding.
Procedure:
1. Remove the electrical and pneumatic supplies from the
TopControl.
2. Pull off the pneumatic hose between TopControl and drive unit at
control connection of drive unit.
3. Control function A:
Pressurize the lower control port of the actuator with
compressed air (6 bar), so that the valve disk is lifted
from the valve seat and is not damaged.
Control functions B:
No compressed air must be applied.
4. Remove the actuator in the open valve position by
unscrewing the threaded nipple from the housing.
5. Before reinstalling the actuator (in the open valve
position), grease the nipple thread with stainless steel
lubricant, e.g. Klüberpaste UH1 96-402 from Messrs. Klüber.
and replace the graphite seal.

ATTENTION! For special applications such as for oxygen and analysis, use only the approved
lubricants.
6. After tightening the threaded nipple, align the control ports by turning the actuator.
ATTENTION! During this operation, the valve must be in the open position.
NOTE For applications in aggressive media, we recommend attaching all free pneumatic
connections to a pneumatic hose whose other end lies in a neutral atmosphere.
