Steam Capacities — Reduced Port lbs./hr. (kg/hr.) Models 2100, 2200, 2300
Note: Capacity based on saturated steam at valve inlet. Pressure differential must be at least 15 psi (6.9 bar) for valve to operate.
†For inlet pressures below 30 psig (2.1 bar), refer to the Low Pressure Steam Capacity Chart, Models 2150 and 2250, page 48.
††When the outlet steam pressure is 50% or less of the inlet pressure, always use the lowest outlet pressure shown in the capacity table.
