Common Questions
- Is this full port or standard port?
- Full port. The ball bore matches the 1/2" pipe ID, so the valve adds almost no restriction — the right choice for pump suction, main shutoffs, and any run where you cannot give up head.
- 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?
- No. This is a leaded model and cannot be installed in US potable-water systems. Watts builds a lead-free (LF-prefix) equivalent for potable service.
- What's the steam rating?
- 150 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.
