5.2 Commissioning, service and maintenance
5.2.1 Commissioning
5.2.1.1 Installation instructions
Fitting position
Unidirectional disc valves are preferably fitted vertically, with a flow from bottom to top.
Other installations are possible, but the fitting’s function must be thoroughly checked in operation.
NOTICE
The flow should generally run along the direction of arrow A.
With horizontal installation, a small amount of fluid remains in the sphere in the casing.
5.2.1.2 General welding guidelines
Sealing elements integrated in weld components must generally be removed prior to welding. To
prevent damage, welding should be undertaken by certified personnel (EN ISO 9606-1). Use the TIG
(Tungsten Inert Gas) welding process.
CAUTION
Damage and injuries due to high temperature supply
To avoid a distortion of the components, all welding parts must be welded to stress-relieved.
Allow all components to cool before assembling.
NOTICE
Damage due to impurities
Impurities can cause damage to the seals and seals area.
Clean inside areas prior to assembly.

Operating instruction | Betriebsanleitung5 | Function and operation

5.2.1.3 ATEX - Guidelines
For valves or plants/installations that are operated in the ATEX area, sufficient bonding (grounding)
must be ensured (see valid ATEX Guidelines EG).
5.2.2 Service
Maintenance interval
The maintenance intervals depend on the operating conditions "temperature, temperature-intervals,
medium, cleaning medium, pressure and opening frequency". We recommend replacing the seals 1-
year cycle The user, however should establish appropriate maintenance intervals according to the
condition of the seals.
RECOMMENDATION
Replacement of seals
To achieve optimal maintenance cycles, the following points must be observed!
a) When replacement of seals, all product-contacting seals should be replaced.
b) Only original spare parts may be installed.
