The TDM valve should be installed as close as possible to the discharge port of the centrifugal pump, preferably directly on the pump discharge port of the pump.
To avoid frequency interference due to pressure oscillations in the medium, the distance between the pump outlet and the valve inlet should not exceed 3m.
Take care to ensure a straight inlet section. Exceptions have to be confirmed to SCHROEDAHL.
Vertical installation is preferred, but horizontal installation is also possible upon request. TDM valves operate at a low noise level and ensure a high reliability due to their sturdy design.
The recommended filter at the pump inlet should have a mesh size of 0.3 to 0.5mm. A smaller mesh size of 0.1mm is recommended for commissioning
