6 Installation at Site
40 of 60
Provide the following straight minimum upstream stabilisation distances free from
any source of potential interference, irrespective of the installation position:
▪ At least 5x DN between BOA-RVK and single sources of interference such as 90°
bends, branches or open shut-off valves.
▪ At least 5x DN between BOA-RVK and turbulence-producing elements such as
pumps or control valves
▪ At least 2x DN downstream of BOA-RVK
6.7 Strainers to DIN/EN
6.7.1 BOA-S
Install the strainers in such a way that the fluid flows through the screen from the
inside towards the outside (cage effect of the screen).
Strainers should be installed with the screen facing downwards to allow thorough
cleaning.
NOTE
For installation in vertical pipes, make sure that the flow direction is downward.
To ensure an optimum (i.e. high) Kv value, make sure when replacing the screen that
the new screen is not installed with the weld seam pointing towards the strainer's
outlet port.
Shut-off valves should be installed in the pipeline on both sides of the strainer so that
the screen can be replaced or cleaned without having to drain the entire system.
Install the strainer in such a way that sufficient clearance is available to remove the
screen.
