What is psi and CWP on a ball valve?
A ball valve’s PSI measures the pressure of the media that flows through the valve as it comes in contact with a square inch of pipe or other fittings. Cold working pressure (CWP) indicates the valve’s maximum pressure rating at temperatures between -20°F to 100°F. This is commonly referenced alongside the valve’s pressure rating.
What do wog and CWP mean on a valve?
Both WOG and CWP refer to the pressure rating of the valve. 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 SWP mean on a ball valve?
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. This might also be marked as SWP, meaning steam working pressure.

What does 600 CWP stand for?
Both WOG and CWP refer to the pressure rating of the valve. 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 CWP mean in valves?
Cold working pressureCWP & WOG Ratings Cold working pressure (CWP) indicates the valve's maximum pressure rating at temperatures between -20°F to 100°F. This is commonly referenced alongside the valve's pressure rating. For example, 720 CWP indicates the valve is rated to 720 PSI within the CWP temperature range.
What is a 600 ball valve?

What is valve rating?
Valves are also rated by the CWP rating. This rating represents the maximum allowable working pressure at the ambient temperature to which the valve may be subjected in normal service. Sometimes it is referred to as cold rating. The pressure rating of a valve at —20 to 100°F (—29 to 38°C), as listed in ASME B16.
What are the types of ball valves?
There are three different patterns available in an American ball valve: full port type, reduced port type, and Venturi port type. The full port type has an internal diameter that's equal to the internal diameter of the pipe.
How do you read a valve tag?
The tag itself should identify the valve, usually by showing the valve number. The type of valve and the system the valve is part of typically are identified. For example, the valve tag might read "200# Main Steam Shut Off." This identifies the valve as the shutoff valve in the 200-pound main steam line.

What do valve classes mean?
It defines three types of classes: standard, special, and limited. ASME B16. 34 covers Class 150, 300, 400, 600, 900, 1500, 2500, and 4500 valves. It also allows valves to be classified as intermediate whose pressure- temperature ratings may fall within those listed for the standard and special class valves.

For example, the valve tag might read "200# Main Steam Shut Off." This identifies the valve as the shutoff valve in the 200-pound main steam line.
What does a 600 CWP mean?
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 WSP mean in valves?
WSP. 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.
Do brass valves have markings?
You may have noticed that brass and stainless steel ball valves have markings on them. These markings aren’t random , they help show what standards ball valves have been tested to and what applications they can be used in. In this blog we will go over the different markings that you may come across when looking at metal ball valves.
Can valves be used in combustible gas?
Not all valves are approved to be used in combustible gas applications. Ones that are, will have specific markings depending identifying where they can be used.
What size is a C x C valve?
Made of lead free brass, C x C valves are available in ½, 3/4 and 1 in. diameter sizes and meet ANSI B1.20.1 and MSS-SP-110 standards. IPS valves are available in diameter sizes ranging from ½ in. up to 2 in. C x C valves consist of two-piece body with blow-out proof stem.
What is a 750LF IPC CXC?
750LF IPC-CXC Ball Valves are made of lead free brass and conform to ANSI B1.20.1 (thread ends) and MSS-SP-110 specifications. They are comprised of a two-piece body and come with a blow-out proof stem.
What does CWP mean in psi?
The CWP rating means Cold Working Pressure, i.e. below 38C and is in psi. Hence temperatures above this you need to check with the vendor. These tend to be instrument systems and hydraulics where having a high rating costs pennies more than a lower rated valve, but pressures of 3-5,000 psi are not uncommon.
What is the difference between CWP and WOG?
CWP is cold working pressure, and WOG is simply Water, Oil, Gas. ANSI, in this sense, is a more comprehensive standard that takes into account more factors, which makes it unfeasible to try to match it up against WOG or CWP.
What is the psi rating for API 6A?
Ratings normally seen are 3,5,10, 15 and 20,000 psi. The sizes of the flanges and pipe is completely different to ASME B 16.5.
What appendix does a limited class valve use?
Limited class valves are not interpolated like most other in-between classes like class 200 but instead use a B16.34 appendix to do some calculations on cross sectional area ratios to justify a little higher ratings than a straight interpolated class.
Is class 800 part of normal specification?
Else 'class 800' (only) could easily be misinterpreted as 'part of normal specification valid, but other (unspecified!) parts not valid' or alternatively understood as 'full specification valid, without any diversion allowed' (and also perhaps inclusive additional 'norms' that the company normally uses but dont bother to mention, because it is assumed that 'everyone' already have a pre-knowledge of this.)
Is Class 800 a class rating?
No. Class 800 is a class rating in 16.5 (I think, but it's late here and my laptop is turned off), though very rarely used and as far as I can tell only for small instrument valves. Class 125 and 250 is another that is rarely used for steel but common in cast iron. CWP 6000 is a pressure rating.
What does WOG mean in valves?
The WOG rating basically stands for Water, Oil, and Gas, and it represents the maximum pressure per square inch that the valve in question can handle. Every valve is given a WOG rating, and caution should be exercised to ensure that that rating is not exceeded at all costs.
What does the WOG mark on a valve mean?
Body Material: The WOG marking also indicates the nature of the atrial used to make the valve. For instance, if you see a marking like CFM8, then that is an indication that the cast used in the construction of the valve is cast 316 stainless steel. Materials do matter a lot, and it would serve your interest to know what you are buying.
Who Decides the WOG Markings?
They are a set of rules that guide them, and these rules are set and arbitrated over by a number of global organizations that bring together manufacturers and suppliers of valves. These bodies include the following.
How to tell if a valve is lead free?
To tell whether a valve has lead or not, simply look at the WOG marking. If you see the initials “LF” then that means that the valve in question is lead-free.
How to know if a valve is compatible with a door?
For the valve to fit, there has to be compatibility, and the easiest way to figure this out is by reading the markings . WOG markings, among others, also indicate the mounting information that is ISO standardized. Before mounting the valve to the actuator, check out the information on the valve.
What is the difference between a stronger and weaker WOG rating?
When it comes to the designation of the ratings, each material is granted value depending on the materials used in their construction. Stronger materials are given a higher WOG rating, while the weaker ones are given a lower one. In the event that the values indicated are exceeded, the valve will run the risk of not working properly, and this could lead to permanent damage, which may in turn cause accidents.
What is a WOG rating?
WOG ratings, and any other ratings used for valves, are an important part of the whole process. It displays all the information needed to know exactly what and where the valve will be used for. If you are planning to get valves for any large or small-scale operations but are lost on where to start, then check out our website at any time of the day and have all your questions addressed fully.
