Flowserve MK 20 - Manual (Page 12)

Thermostatic steam traps with corrosion-resistant membrane regulator
unaffected by waterhammer. Particularly suited for steam heating plants
and other low-pressure steam installations.The standard design features
a 5U2 capsule (undercooling) and discharges condensate at approx.
30 K (degC) below the saturated steam temperature.
Steam traps equipped with 5N2 capsules discharge condensate at
approx. 10 K (degC) below the saturated steam temperature.
The trap is supplied as a straight-through valve. It can be turned into an
angle valve by changing the position of the plug .
