Quality Flow Controls LLC: Brass and Copper Isolation ValveInstallation of the 2-Port Isolation Valve (2PIV) provides quick and easy refrigerant leak detection in evaporators, condenser coils, and refrigerant line sets. According to the manufacturer, faster results are now possible when searching for leaks in hard-to-reach locations, such as ceilings, walls, attics, or crawl spaces, providing 100 percent successful results for the technician. Valves are brazed on the suction and liquid lines, just ahead of the evaporator and condenser. Service gauges are connected to the valves. The system is then pressurized with nitrogen, and each valve closed, isolating the four circuits, providing easy determination of the leak’s location through pressure loss. Easily installed in any position or direction, the 2PIV can remain in place without any loss of performance to the system, the company said. The method saves time and money by eliminating guesswork. HVAC companies now have the ability to flat rate this task, said the manufacturer.
