4.2 Function
During heating up, the heated liquid expands. If the system pressure exceeds
the corresponding response pressure, the diaphragm safety valve opens and
protects the system against overpressure. Liquid is discharged until the pres-
sure in the system has dropped below the maximum permissible pressure.
The heating 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.

• Pressure Equipment Directive (2014/68/EU)
