LAC stands for Low Ambient Control. The LAC-4 is a three way modulating valve that responds to discharge pressure. The LAC valves are available with three standard settings which should handle the majority of applications: 100 psig for R-134a; 180 psig for R-22, R-407C and R-502; and 210 psig for R-402A, R-404A and R-507. The LAC valves can also be used with other commonly used refrigerants including R-401A. Generally, standard settings may be used for these refrigerants but special settings may be preferred for some applications.

Note: This item does not come with a strainer.
