For pressure & temperature ratings see indication on trap body (DN 50 – DN 125) or specification on
the name plate (DN 150 to DN 1200).
According to EN 19 the following indications are stated on the name plate:
■ Manufacturer’s brand
■ Type designation
■ Pressure class PN or Class
■ Material number
■ Max. temperature

Corrosion Resistance
When used for its intended purpose the safe functioning of the valve will not be impaired by corrosion.
Sizing
The valve body must not be subjected to sharp increases in pressure. The dimensional allowances for
corrosion reflect the latest state of technology.
