    Nominal pressure PN 16 to 40 · Suitable for liquids, gases and vapors up to 350 °C The valve opens when the upstream pressure rises. NOTICE The Type 41-73 Excess Pressure Valve is not a safety valve. If necessary, a suitable overpressure protection must be installed on site in the plant section. 2.1 Transportation and storage The regulator must be carefully handled, transported and stored.
