Common Questions
- Is this full port or standard port?
- Full port. The ball bore matches the 3" 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.
- Can I actuate this valve?
- Yes. The body has integral actuator mounting pads, so an electric or pneumatic actuator bolts straight on without a bracket kit. For a ready-to-wire assembly, look at the LFEMVII electric ball valves.
- What's the steam rating?
- 125 psi WSP (saturated steam). Do not size steam service off the 1000 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.
