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.
- 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.
- 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.
