We have included that argument among others. This is not the first issue we've had with them regarding what the codes and standards as they are their own approving jurisdiction.

I've been trying to find one at the request of a customer for use as control valves for the underground firewater piping of an industrial facility. We've gone around and around ad nauseam but they don't want butterfly or gate valves because in their words they, "don't want to dig up the valve when it no longer seals". Ball valves that size normally require a ~3' long handle and show the handle almost directly fastened to the valve body itself. Gearboxes could be used at valve level, but I still need to extend the handle of the gearbox above grade in such a way as to indicate the valve position. Anyone out there with any experience with this scenario? Ryan L.
