"1000 WOG" is not a model number, but indicates that the maximum working pressure of the valve is 1000 psi for water, oil, and gas media.
WOG stands for Water, Oil, and Gas, meaning the valve or fitting is suitable for use with water, steam, oil, and gas media. It usually appears together with a pressure value, such as "1000 WOG".
Application Scenarios:
A valve marked with 1000 WOG indicates that it is suitable for the following conditions:
Water piping systems (cold water, hot water), oil piping systems (lubricating oil, fuel oil, etc.), gas pipelines (non-corrosive gases). This is commonly found on ball valves, gate valves, check valves, and other valve products.
| Unit: psii | Unit: bar | Unit: MPa | Applicable Media | Corresponding products |
| 200 | 13.8 | 1.38 | Water, Oil,Gas | Commonly found in small-diameter, low-pressure pipelines |
| 300 | 20.7 | 2.07 | Water, Oil,Gas | Household and light industrial pipelines |
| 400 | 27.6 | 2.76 | Water, Oil,Gas | Some industrial water and oil pipelines |
| 600 | 41.4 | 4.14 | Water, Oil,Gas | Medium-pressure industrial pipelines, commonly using ball valves |
| 800 | 55.2 | 5.52 | Water, Oil,Gas | Medium-to-high pressure pipelines, some flanged valves |
| 1000 | 68.9 | 6.89 | Water, Oil,Gas | High-pressure pipelines, industrial valve standards |
| 1500 | 103.4 | 10.34 | Water, Oil,Gas |
High-pressure industrial pipelines, heavy-duty valves |
Additional Notes:
1. Temperature affects pressure: The pressure indicated by WOG is generally at room temperature (20-25°C). The valve's pressure tolerance decreases as the temperature increases.
2. Applicable media: WOG is suitable for water, oil, and gas, but not for corrosive liquids or ultra-high temperature steam. The valve body material needs to be considered.
3. Actual selection: When selecting a valve, it's best to allow for a safety margin. For example, a 1000 WOG valve can be used for applications with pressures ≤ 700-800 psi.
