Installing the valve
7.2.3 Weld the valve body into the pipeline
DANGER!
Risk of injury from high pressure.
▶ Before working on the system, switch off the pressure and
vent or empty the lines.
NOTE!
The electronics in the actuator will be damaged by the effects of
heat.
• The actuator must be removed before the valve body is
welded in.
Preparation:
1. C lear impurities from pipelines (seal material, metal chips, etc.)
2. I nstall filter: Required for devices with approval as per EN 161.
According to EN 161 "Automatic shut-off valves for gas burners
and gas appliances", a dirt trap, which prevents the penetration
of a 1 mm test pin, must be installed upstream of the valve in
the pipeline.
3. Consider installation conditions.
NOTE!
The following must be heeded when installing the device in
the system.
The device and relief bore must be accessible for inspections
and maintenance work.
Installation position: Arbitrary, ideally with actuator facing
upwards.
Pipelines: Ensure that pipelines are in alignment.
Flow direction: indicated on the type label with an arrow and the
digits 1 and 2. The 1 and 2 are also on then valve body for iden-
tification. The flow direction is below the seat with flow direction
from connection 2 to connection 1.
Welding:
→
Weld the valve body into the pipeline.
Ensure that there is no voltage present and minimal
vibration during installation.
Next steps:
Mount the actuator on the valve body, carry out the electrical
connection, run the X.TUNE function, set the AUTOMATIC oper-
ating state.
7.2.4 Installing actuator on valve body
Preconditions: MANUAL operating state, valve position at least
1/3 open, supply voltage switched off.
→
B efore installation the actuator, check whether the graphite
seal for the valve body is present and undamaged.
→
Replace damaged or missing graphite seal.
