Engineering notes
Mounting location

Dirt trap

Cavitation

Preferably mount the valves at the return, as the temperature is lower there and
the strain on the stem sealing gland is lower.
Operate valves of the product lines VVF43.. with inverted flow direction for steam.
Mount a dirt filter or dirt trap before the valve to ensure proper functioning, and a
long service life of the valve. Remove dirt, welding beads, etc. from the valves and
pipes.
Cavitation can be avoided by limiting the pressure differential across the valve
depending on the medium temperature and the prepressure.

Mounting notes

Mounting positions apply to both 2- and 3-port valves.
Commissioning notes
The valve may be put into operation only if actuator and valve are correctly
assembled.

Ensure that actuator stem and valve stem are rigidly connected in all positions.

Maintenance notes
The valves are maintenance-free.
When servicing valves or actuators:
Deactivate the pump and turn off the power supply
Close the shutoff valves
Fully reduce the pressure in the piping system and allow pipes to completely
cool down
Disposal

If necessary, disconnect the electrical wires.
Due to the different types of material used, the valve must be disassembled prior to
disposal. Special handling of certain valve components may be required by law or
may be sensible from an ecological point of view.
Local and currently valid legislation must be observed.

Warranty
Application-related technical data are guaranteed only when the valves are used in
connection with the Siemens actuators listed under ”Equipment combinations”,
page 3.
When used with actuators of other manufacture, any warranty by Siemens
becomes void.
