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. They are found on the valve body as a number with either WOG or CWP under it. The number represents the pressure rating, ie a 600 with CWP under it would mean the valve is rated to 600 PSI CWP.
What does WOG rating mean?
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 is a 200 WOG valve?
This 1.5-inch angle valve is marked “200 WOG” (and “125 WSP”), not “200 PSI.” Pipefitters classify valves by their pressure and temperature limitations. The Steam Working Pressure (SWP) rating, sometimes known as Working Steam Pressure (WSP), indicates the maximum allowable pressure from hot, vaporized water.
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.
What is the difference between a gas ball valve and a water ball valve?
This stands for Water, Oil or Gas. Most gas valves are brass and much heavier than standard valves, The other difference is most gas valves open or shut off with 1/4 turn. Ball valves also work the same way. Using a gas valve for water is more preferable than using a water valve for gas.
What does 600w OG mean?
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.
What does a ball valve do?
Ball valves use a metal ball with a hole bored through the center, sandwiched between two seats to control flow. Used in many hydrocarbon process applications, ball valves are capable of throttling gases and vapors and are especially useful for low-flow situations.
What is the difference between ball valve and gate valve?
The main difference is in the operation. A gate valve moves a solid disk up and down to open/close the orifice. A ball valve rotates a ball (the orifice) with a bore in it 90 degrees to open/close the valve.
What does wog and WSP stand for in plumbing?
Common (sometimes older) ratings are WOG and WSP (or sometimes SWP). WOG stands for the water, oil, and gas rating for the valve and reflects the maximum pressure capability of the valve at 100 F. WSP stands for working steam pressure and reflects the maximum pressure rating for the valve at the highest temperature rating.
What does Wog stand for in valve rating?
WOG stands for the water, oil, and gas rating for the valve and reflects the maximum pressure capability of the valve at 100 F. WSP stands for working steam pressure and reflects the maximum pressure rating for the valve at the highest temperature rating.
What does branch water piping mean in plumbing?
Branch Water Piping – The local domestic water piping that extends from the vertical risers (or other mains) and supplies water to plumbing fixtures or equipment. Brass Seats and Seals – In a plumbing valve the surface area on the moving part of a valve and the stationary part of the valve.
What’s the difference between Wog, SWP and cold working pressure?
A variety of abbreviations correspond to WOG and SWP, but Cold Working Pressure (CWP) may be the most accurate term to describe pressure limits at standard temperatures
