Watts LF123LP 3/4 Lead-Free Pressure Reducing Valve, Copper, NPT

The Watts LF123LP 3/4 is a 3/4" lead-free pressure reducing valve with NPT connections. It reduces inlet pressure of up to 200 psi to an adjustable 10-30 psi downstream, factory set at 25 psi. It features a copper body and a epdm seat. Rated to 200 psi. This model is certified lead-free for potable-water installations.

This 3/4 inch lead free low water pressure regulator is used in residential and point of use applications to regulate water pressure in piping systems that require low pressure regulation. This regulator is serviceable in-line. It consists of a lead free body construction, NPT threaded female connections, stainless steel seat, stainless steel integral strainer, reinforced EPDM diaphragm, and EPDM valve disc. The adjustable reduced pressure range is 10 to 30 psi (0.68 to 2.0 bar) and is factory set at 25 psi (1.7 bar).

Features

• Lead free body construction
• Integral stainless steel valve seat
• Integral stainless steel strainer
• Serviceable in-line
• Includes: Strainer

Common Questions

Does it have a built-in bypass for thermal expansion, or do I still need an expansion tank?

No - LF123LP 3/4 does not include a thermal-expansion bypass. Once this valve is installed the system downstream of it is closed, so a thermal expansion tank (and, where required, a relief valve) must be installed to absorb expansion from a water heater. If you want the bypass built in, choose the -B version of this model.

What pressure is it set to out of the box?

LF123LP 3/4 ships factory set at 25 psi. The adjustable reduced-pressure range is 10 to 30 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.

Does it include a strainer?

Yes - LF123LP 3/4 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.

Does it come with a gauge?

No - LF123LP 3/4 has no gauge and no gauge tapping. Set the outlet pressure using a gauge elsewhere on the downstream piping. The -GG version of this model ships with a gauge tapping and a 160 psi gauge.
