What does WOG mean on ball valves?
water, oil, gas
WOG (water, oil, gas) is an older term that is no longer used as frequently as it once was. It simply means that the valve is intended for use with water, oil or gas, with the exception of combustible gases.
What is WOG rated?
Water, Oil and Gas
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. U.S. Valve offers 400 WOG, 600 WOG, and 1,000 WOG ball valves.
What does WOG pressure mean?
WOG stands for Water, Oil and Gas and is the non-shock pressure rating for valves at an ambient temperature.
How much pressure can a ball valve handle?
Ball valves are extremely versatile as they can handle pressures up to 1000 bars and temperatures up to 400 degrees.
What ball valves are rated for natural gas?
The Apollo 80-100 Series is easily one of the best bronze ball valves on the market that is specifically designed for natural gas applications. The Apollo 80-100 is UL Listed for LP- Gas, natural gas, and flammable liquid and heated oil.
How much pressure can a brass ball valve hold?
Rated at 600 PSI (water, oil, and gas), these full port valves are strong enough for many applications.
How are valve ratings calculated?
The basic valve sizing equation Q = Cv√∆P can be used to calculate pressure drop, flow rate, or the flow coefficient. For solutions other than water, a correction for a difference in specific gravity of the solution is necessary. This revised formula would be: Q = Cv[√∆P/Sg] with Sg = specific gravity of the liquid.
Can any ball valve be used for gas?
Any ball valve bearing the ½ PSI and 5G- ratings are strictly used for indoor gas applications.
How do you calculate valve pressure ratings?
The relationship of NPS to DN can roughly be calculated as DN = NPS x 25. As NPS increases, the pressure rating of the flange decreases. In addition to flange sizes as measured in NPS, flange thickness can also vary and must be taken into account.
How do you calculate rated valve capacity?
The volume flow rate for liquids can be calculated by multiplying the fluid velocity times the flow area. Thus, Cv is numerically equal to the number of U.S. gallons of water at 60°F that will flow through the valve in one minute when the pressure differential across the valve is one pound per square inch.
What is valve pressure rating 300?
the class 300 flange (bigger and stronger, but with the same bore size) withstands 570 psi at the same temperature of 600 degrees F° finally, a class 2500 flange of the same size bears 34 times more pressure than the class 150 rated flange, reaching a whopping 4730 psi rating at 600 F°!
