COMMISSIONING

Installation of the valve
Installation in any orientation but preferably with the actuator above.
Clean piping from contamination!
Clean piping from contamination!
Before attaching the valve housing, make sure the piping is
aligned!
If the housing is to be welded on, make absolutely sure that
the actuator is removed beforehand.
Devices with Approval DIN EN 161: According to DIN EN 161
"Automatic Shut-off Valves for Gas burners and Gas
appliances", a dirt trap must be connected upstream of the
valve. The dirt trap must prevent the penetration of
a 1 mm test mandrel. In order to maintain approval, also with
stainless steel housing, the user is requested to install such
a dirt trap upstream of the valve.
Procedure:
1. Remove the pneumatic supply and the electrical
connection (if a pilot valve is attached).
2. 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 and I:
No compressed air must be applied.
3. Remove the actuator in the open valve position by
unscrewing the threaded nipple from the housing.
4. 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.
5. 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.
