The Watts LFB6000 4 is a 4" lead-free 2-piece standard port ball valve with female FNPT connections. It features a brass body and a silicone seat. Rated to 600 psi and 0°F to 450°F. This model is certified lead-free for potable-water installations.
This 4 inch lead free two-piece standard port ball valve with female threaded end connections is used in commercial and industrial applications for potable water applications. It features a blowout proof pressure retaining stem, while the standard port orifice ensures minimal pressure drop. The durable seats provide tighter torque and more abrasion resistance for longer lasting service. This valve is individually tested, air under water, both open and closed. The temperature range is 0 to 450 degrees F (-18 to 232 degrees C) at 50 psi (344.7 kPa). The pressure rating is 400 psi (28 bar) WOG non-shock and 125 psi (8.6 bar) WSP.

Common Questions
- Is this full port or standard port?
- Standard (conventional) port. The ball bore is one size down from the pipe, which trades a small pressure drop for a smaller, lighter, lower-torque valve. Fine for isolation duty; specify a full port model if flow is critical.
- Can I use this on natural gas or propane?
- No. This valve carries no fuel-gas listing, and code requires an ANSI Z21.15 / CSA listed valve for natural gas or LP. Use a Watts GBV series gas ball valve instead.
- Is this rated for potable water?
- Yes. It is a lead-free model (weighted lead content at or below 0.25%), so it is legal for potable water. Check the spec sheet if your submittal specifically requires an NSF/ANSI 61 listing.
- What's the steam rating?
- 125 psi WSP (saturated steam). Do not size steam service off the 600 psi figure — that is the WOG/CWP rating (cold water, oil, gas, non-shock).
- Can it be serviced without cutting it out?
- No. A 2-piece body is not designed for in-line rebuild; it is replaced as a unit. Choose a three-piece valve (LFB6800 / S-6800 series) where in-line serviceability matters.
