• Determine the differential pressure across the trap
(inlet pressure - outlet pressure). On applications where
the steam is controlled by a modulating temperature
regulator, the trap differential should be 1/2 psi (0.34 bar).
• Determine the capacity based on the differential
pressure and the required capacity of the trap to open
against the maximum inlet steam pressure.
• Apply a Safety Factor by multiplying required capacity
by 1.5.
