What is the meaning of 1000 wog?
As stated by JLSeagull, WOG stands for water-oil-gas. It should intend the same as CWP (Cold Working Pressure), that is the maximum pressure rating allowed under normal “ambient” temperature conditions, -29°C to 38°C. 1000 WOG is 1000 psi for gas-oil-water. (Note 2300 kPa = 333.6 psi)
What is wog pressure rating?
The common method of stating the pressure rating of ball valves is in terms of WOG. The WOG rating specifies the maximum pressure per square inch that a valve can handle while the WOG indicates the valve is suitable for Water, Oil and Gas.
What is WSP rating?
The Steam Working Pressure (SWP) rating, sometimes known as Working Steam Pressure (WSP), indicates the maximum allowable pressure from hot, vaporized water.
How much pressure can a ball valve hold?
The ball valve’s ease of operation, repair, and versatility lend it to extensive industrial use, supporting pressures up to 1,000 bar (100 MPa; 15,000 psi) and temperatures up to 752 °F (400 °C), depending on design and materials used. Sizes typically range from 0.2 to 48 inches (5.1 to 1,219.2 mm).
Are ball valves rated for steam?
Ball valves, like all valves, are generally rated at a lower pressure for steam service than for liquid or dry gaseous service. Wet steam is damaging to all valve parts at the moment of opening and closing, or when throttling.
What is the difference between globe valve and ball valve?
The main difference between these two types is the way they close. A globe valve uses a plug (stem) that closes against the flow, and a ball valve has a gate (ball) that closes across the flow. Globe valves are good for regulating flow, whereas ball valves are better for on/off control without pressure drop.
What does 150 PSI WSP mean?
steam pressure
WSP stands for water steam pressure or working steam pressure. It reflects the rating for the valve at water steam temperature. A valve rated at 600WOG/150WSP should be able to withstand 600 psi in a water or gas pipe and 150 psi if used in a steam supply system.
