I would like to know, when designing an air cooled condensing air conditoining system (i.e. Liebert, they
recommend having a shut-off valve on the liquid side down
near the evaporator. Can this valve be an ordinary ball
valve or does it have to be refrigerant rated? What are
some good manufacturers of such valves?
