The suitability of a valve for use with Natural Gas
The suitability of a valve for use with Natural Gas
(OP)
thread378-167629: Valve Class I hadn't come across the WOG term before on valves here in Australia and saw a SATURN valve with 2000 wog on it today. Thanks to this forum and a very good link, I'm enlightened. But, if I read correctly, the wog term does not imply that the valve is approved for use with a particular medium, e.g. Natural Gas (Methane)but it can be.
Does anyone have a view on this?
I checked the approval directories for gas components here in Australia (all 3 of them) and couldn't find the Apollo Saturn valve listed. The valve I saw read "SATURN" 2000 wog, was 1/2 " NPT and was operating at 200 kPa (30 psi).

2000 WOG would stand for 2000 PSI Cold Working Pressure in "Water, Oil, or Gas" service hence the WOG.
I don't specifically remember which MSS standard it would be but I think it's MSS SP-110 for ball valves.
Note that MSS SP-110 is not a listed standard in Table 326.1 of ASME B31.3 so these would be treated as unlisted components. I can't comment on whether they are acceptable for use in Australia under your pressure equipment regulations.
RE: The suitability of a valve for use with Natural Gas
My decision is that the valve can not be used on Natural Gas infrastructure because it ahs not been approved under a "type testing" regime in Australia.
