What are severe service ball valves?
Severe service refers to the challenges levied on the valve itself, such as very high pressures and temperatures. Critical service refers to the potential consequences of the valve not working properly.
What do the different color handles on ball valves mean?
So what do these colors on the handle mean anyway? It means nothing really, We have used red for hot and blue for cold, However, do not take that as the norm, MOST of the time it is just the decision of the plumber or the manufacturer as to the color of the handle.
Does direction matter on a ball valve?
In short: a ball is round so direction does no matter. If a valve must be installed in a certain direction is should have an arrow cast into the body showing the direction of flow.
What does severe service mean?
A severe service schedule recommends that things like an oil change, air filter replacement, and transmission service be done more often: either in fewer miles or in less time.” Foreign and domestic manufacturers create a specific schedule for each vehicle they manufacture.
What does 600 CWP mean on a ball valve?
CWP stands for Cold Working Pressure and is an indication of the pressure rating for valves at a temperature up to 100°F. The number represents the pressure rating, ie a 600 with CWP under it would mean the valve is rated to 600 PSI CWP.
Can you reverse handle on ball valve?
Reverse handle application threaded brass ball valves. Apollo is an industry leader for ball valves. It works opposite of a normal ball valve. When the handle is parallel with the pipe, it is closed and when it is perpendicular, the valve will be open.

What does WSP stand for in steam valves?
WSP stands for Working Steam Pressure and defines the pressure of steam in a system that a ball valve can be used in. The industry uses WSP for bronze ball valves because, as the temperature rises, the strength of the material decreases. Not all valves are approved to be used in combustible gas applications.
What does a 600 CWP ball valve mean?
The number represents the pressure rating, ie a 600 with CWP under it would mean the valve is rated to 600 PSI CWP. WSP stands for Working Steam Pressure and defines the pressure of steam in a system that a ball valve can be used in.
What does Wog mean on a ball valve?
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. Working steam pressure (WSP) indicates the maximum steam pressure that a ball valve can withstand at the highest temperature rating.
What do the letters wog and WSP stand for?
For safety’s sake, each valve used in fire protection – from control valves to the trim valves used to drain and test sprinkler and standpipe systems – should be used only at pressures the valve can safely withstand. Often, however, the letters “WOG,” “CWP,” “WSP,” or other abbreviations, along with a number, are imprinted or cast on the valve.

Which is higher wog or WSP for valve?
The WOG rating is always higher than the WSP rating for a valve or fitting. SWP: Steam Working Pressure: This designates the maximum recommended steam pressure a product can operate at. CWP: Cold Working Pressure: This designates the maximum non-shock pressure a product can operate at.
