Corrosion Resistance

When used for its intended purpose the safe functioning of the steam trap will not be impaired by

corrosion.

Pressure / Temperature Ratings

UNA 2... without sightglass cover:

For pressure / temperature ratings see indications on trap body or name plate: pressure class

PN / Class, material number, max. temperature, max. pressure, max. differential pressure.

UNA 23h/v: max. admissible temperature: 300°C

UNA 25h/v: max. admissible temperature: 350°C

UNA 26h stainless steel: max. admissible temperature: 300°C

UNA 26h/v: max. admissible temperature: 400°C

UNA 23h/v with sightglass cover: max. admissible temperature: 240 °C

Reduced temperature limits for sightglass cover with integrated reflexion water level indicator.

If the pH value is above 9.0 and the fluid temperature exceeds 200 °C the glass will get more wear.
