1700
Orifice Capacities
ASME, B & PVC, Section I rating - 2001 Edition
pounds per hour saturated steam at 3% overpressure,
90% of actual capacity
W=51.5KAP for “P” less than or equal to 1580 psia K=.878 (4" Q — K = .792)
W=51.5KAP x [.1906P-1000/.2292P-1061] for ”P” greater than 1580 psia
A= flow area in sq. in.
P= (1.03 x set pressure) + 14.7
Apply correction factor for capacities on superheated steam. Correction factor tables begin on page 1700.66. Review pressure temperature limits. Pressure
temperature tables begin on page 1700.32. The 1700 is certified as a restricted lift valve and capacities can be restricted down to 30% of its full rated capacity.
