It reduces inlet pressure of up to 400 psi to an adjustable 25-75 psi downstream, factory set at 50 psi. It features a copper body and a epdm seat. Rated to 400 psi. This model is certified lead-free for potable-water installations.\u003c\/p\u003e\u003cp\u003eThis 3\/4 inch lead free water pressure reducing valve is used in commercial and residential applications to reduce incoming water pressure for protection of plumbing system components and to reduce water consumption. It consists of a lead fee cast copper silicon alloy body, integral stainless steel strainer and thermal expansion bypass. It features double union PEX end connections. The maximum working pressure is 400 psi (27.6 bar), and may be adjusted from 25 to 75 psi (172 to 517 kPa). The standard setting is 50 psi (345 kPa). All parts are quickly and easily serviceable without removing the valve from the line.

When downstream pressure from a water heater rises above the inlet pressure, the bypass relieves that excess back through the valve toward the supply, which prevents nuisance pressure build-up on a closed system. It is not a substitute for a properly sized thermal expansion tank where your local code requires one - the bypass only relieves back to the street when street pressure is lower, so check the code in your jurisdiction.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat pressure is it set to out of the box?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eLFN45BM1-DU-PEXXPEX US-QAD ships factory set at 50 psi. The adjustable reduced-pressure range is 25 to 75 psi, so you can dial the outlet anywhere in that band on site with the adjusting screw - loosen the locknut, turn in to raise pressure and out to lower it, then retighten and verify with a gauge.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eDoes it include a strainer?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes - LFN45BM1-DU-PEXXPEX US-QAD has an integral stainless steel strainer built into the body, so you do not need a separate inline strainer ahead of it. The strainer is removable for cleaning; if the valve starts to lose downstream pressure, pull and rinse the strainer before assuming the seat has failed.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eDoes it come with a gauge?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eNo - LFN45BM1-DU-PEXXPEX US-QAD has no gauge and no gauge tapping.
