Capacities and Selection<br />
Capacity in Tons of Refrigeration<br />
These ratings are based on vapor free (subcooled) liquid refrigerant entering<br />
the expansion valve (86°F for Refrigerant 717) and standard factory setting.<br />
Because of the artificial superheat provided by the electric heater the Level-<br />
Master will have a greater capacity than a conventional thermostatic expansion<br />
valve. For selections for other refrigerants, contact Sporlan Valve<br />
Company, Washington, Missouri 63090.<br />

These factors include corrections for liquid refrigerant density<br />
and net refrigerating effect, and are based on an average evaporating<br />
temperature of 0°F. However, they may be used for any<br />
evaporator temperature from -40°F to 40°F since the variation<br />
in the actual factors across this range is insignificant.<br />
EXAMPLE: At -20°F evaporator, 160 psi pressure drop and 50°F liquid<br />
temperature, the capacity of an LMC-DA-10 (for ammonia) is<br />
12.6 x 1.11 = 14.0 tons.<br />
Ordering Instructions<br />

1. Valve type, per specification table. If an external equalizer is<br />
required, add "E" as the sixth letter. EXAMPLE: LMC-AAE-20<br />
2. Connection sizes and tubing lengths, if other than standard.<br />
