Corrosion Resistance

The valve body must not be subjected to pulsating loads. The dimensional allowances

for corrosion reflect the latest state of technology.

Sizing

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

impaired by corrosion.

Admissible differential pressure

)

Differential pressure ∆PMX 22 barg (319 psig)
