4.2 Function
When the solar liquid in the system heats up, it expands. The pressure in the
system increases. When the maximum permissible pressure in the system is
exceeded, the spring and the diaphragm integrated in the installed product
are pressed back. Liquid is discharged until the pressure in the system has
dropped below the maximum permissible pressure.
The heat capacity of the system to be safeguarded determines the inlet size
of the product.
The inlet size, the outlet size, the nominal pressure and the application area
are indicated on the cap of the product and on the adhesive label on the pack-
aging.
