      This 3/4 in. lead free cartridge style water pressure reducing valve is designed to reduce incoming water pressure to protect plumbing components and reduce the water consumption for commercial, industrial and residential applications. It features a lead free brass body, thermoplastic seat cartridge, NPT threaded union inlet and NPT female outlet connections, reinforced diaphragm, and a bypass valve to control thermal expansion pressure. The reduced pressure rating is set at 50 psi (345 kPa). The maximum working pressure is 400 psi (27.6 BAR) and temperature range is 33 to 180°F (0.5 to 82°C).

      • NPT threaded union inlet by NPT female outlet
      • Great flow performance with low fall off pressure
      • Bypass valve controls thermal expansion pressure
      • Sealed spring cage for accessible outdoor or pit installations

      Functions as described in manufacturer's specs. Compared to 20-year old worn out valve it replaced, it 1) Holds pressure at set point overnight in no-usage situation, instead of creeping up to city water main pressure. 2) Does not restrict flow much under moderate-usage conditions--when using water two different places, like someone watering the lawn with a garden hose and someone else using the kitchen sink, there is NOT a noticeable pressure drop. The Home Depot product title as it is listed above at this time is incorrect. It says "3/4 IN. LEAD-FREE BRASS MPT X FPT PRESSURE REDUCING VALVE". It actually has 3/4 in FPT (female pipe threads) on both sides. One side has a union connection. The union connects to the valve by a large brass nut. The female threads inside the large brass nut engage male threads on the valve. I don't know what size those male threads are, but it's not 3/4" MPT. This product has a flexible design. As far as I can tell, the union could go on either side (inlet or outlet). If you take the union off, both sides are threaded the same (3/4"FPT inside the bore, male threads for union attachment around the outside.) Nice. Or if you had another of the union pieces, you could have it with a union on both sides. If I had it to do over again, I'd try to get one of those. That would have made the installation easier, where it had to go into pre-existing piping where there wasn't much flex in the system on either side. The valve I review here is the Watts LFX65BU. They do have a model number for the double-union version LFX65BDU. I don't where the double-union version is for sale.
