OIL CAPACITIES (U.S. GPM)
APPLICATION: SCREW COMPRESSOR OIL PUMP
RELIEF REGULATOR (HA4AL)
LIQUID CAPACITIES (U.S. GPM)
APPLICATION: REFRIGERANT PUMP RELIEF
REGULATOR (HA4AL)
Capacities assume no gas flashing. No capacity correction
required for temperatures between –40°F (–40°C) and +40°F
(+4.4°C).
Capacities based on oil with less than 300SSU viscosity.
† Bypass from intermediate pressure at saturation temperature to booster suction.
*These capacities are not for hot gas defrost relief. See the chart in the middle of this page.
**Optional 25% and 50% reduced capacity ¾" (20mm) plugs are available.
Discharge gas capacities are based on +15°F (+10°C) evaporator temperature.
*Or an outlet pressure regulator with electric shut-off (HA4AOS).
Evaporator tons at 10°F (5.6°C) TD (temperature differential), valve capacities are conservative. These capacities can be
modified up or down depending on type of evaporator, temperature, mass, frost thickness, defrosting time, etc. Typical
for –20°F (–28.9°C) evaporator.

Hot gas bypass capacities are based on above given temperatures. Liquid
temperature is the same as condensing temperature. Evaporator temperature
+40°F (+4.4°C) or less for +86°F (+30°C) condensing; –22°F (–30°C) evaporator
for +15°F (–9.4°C) condensing.
