Reduced Capacity V-Ports shown in gray.
For best control and modulation, size the MCV valve for both the full load capacity and the minimum load capacity
(weekend load). The minimum load capacity should be at least 15% of the full load capacity. The capacity tables are
conservative, so it is not necessary to add a safety factor for capacity.
Ammonia, R-22 and R-134a capacities assume 86ºF (30ºC) condensing, except -40ºF (-40ºC) assumes +20ºF (-7ºC)
liquid (e.g. two stage). R-404 and R-507 assume 95ºF (35ºC) condensing. For overfeed evaporator suction, add 20% to
the evaporator load or use next larger size valve to accommodate liquid volume.
