Series LF25AUB-Z3 Lead Free* Water Pressure Reducing Valves are used in commercial and residential applications to reduce incoming water pressure to a predetermined level, thereby protecting downstream plumbing system components and reducing water consumption. For versatility, a variety of end connections are available: threaded, solder, PEX, quick-connect, CPVC, Press, or Cold Expansion PEX (ASTM F1960) with union and double union. Standard pressure setting is 50psi with an adjustable range of 25 ‒ 75psi (172 ‒ 517 kPa). For sizes: 1/2 to 2 IN (15 ‒ 50mm). Temperature range is 33 to 180 degrees F (0.5 to 82 degrees C).FeaturesSealed spring cage for accessible outdoor or pit applicationsFor water supply pressures up to 300psiIntegral stainless steel strainer and bypass feature that controls thermal expansion pressureDesigned for easy in-line servicing; has replaceable seat module

An industrial regulator with larger orifices for better flow is the Watts Model 263A. This brass unit also offers an adjustable pressure limit and is available with a pressure gauge.

Because of its size and lighter weight, it is our most popular model and it produced a flow of 4 to 4.5 GPM in out test. As you can see above, you can optimize the Watts 263A to your needs. If the product will be out in the elements, you might consider adding stainless steel external screws and/or a stainless steel, oil filled gauge. Stainless steel will not rust, so it is perfect for leaving outside attached to the hose spigot. The oil in the oil filled gauge will keep the face clear and also dampens vibration during travel. For the ultimate durability, you might select the fully stainless model.
