When a valve manufacturer is API 6D certified it means that they have a certificate that certifies their valves are tested to API standards. There are different specifications of API. For instance, API 6D is a specification for pipeline valves. “API 6D specifies requirements and gives recommendations for the design, manufacturing, testing and documentation of ball, check, and gate valves for application in pipeline systems.”
Not only are our Trunnion ball valves API 6D certified but we also carry the API Q1 specification. This allows us to mark our valves. When you see this mark you will immediately know that GVC valves have been manufactured in a quality management system.
What does it mean to be API 6D and API Q1 certified? Global Valve and Controls is recognized by API and other industries for our product quality. It also means that every single one of our products are marked therefore if any future questions arise of a valve we will know exactly which valve it is.
What does it mean to our clients? Proof that our products are API as well as meet the specifications and our quality is consistent. Our clients are also aware that we have a management system in place that provides any assurances.
In conclusion, we stand behind our products 100%! If you are not satisfied with our service or our products please contact us so that we can fix it immediately.
Many times a customer will call and ask if we can offer any valves for cryogenic service. Cryogenic meaning very low temperatures. We can happily say that we do carry a few valves that are made for such services. Companies that work with LNG (Liquified Natural Gas), oxygen, helium and such are the most common clients that we have that need these specific valves. What makes cryogenic valves different than standard valves? This is possibly one of those most frequent questions asked, and the answer has to do with the temperature. A cryogenic ball valve can fully work in temperatures as low as -320 degrees Fahrenheit and at pressure ratings as high as 750 psi.
GVC Valves series FS525, FS600, YFS and our 790 are all compatible with cryogenic conditions. To learn more please visit our website.
Different types of bores for ball valves – full port, reduce port and V-port. These three types have different constructions and purposes.
Full Port Ball Valve – A full-port, also known as a full bore, ball valve has a bore internal diameter (ID / inside diameter) approximately equal to the pipeline ID. This allows for reduced friction and pressure loss across the valve. With a full port ball valve there is NO restrictions to the flow of medium, but the valve can be more expensive. This type of bore is ideal for situations where pigging may be necessary. Global Valve & Controls (GVC) series CFS and 2T/3T split body and welded design, full port, flanged ball valve combines its sealing technology and design expertise for over 25 years with the versatility to solve even the most demanding applications . This technology and expertise is widely used in the chemical, pulp and paper, petrochemical, food and beverage and refining industries.
Reduce Port Ball Valve – A reduce-port, also known as a reduce bore, ball valve is a valve in which the bore is reduced to one or two nominal sizes lower. This provides a more restricted flow path, generally resulting in higher energy losses. Global Valve & Controls (GVC) series RCFS and R2T/R3T ball valves offer both full port and reduce port valves. Known for its design features , superior sealing areas and various stainless alloys , the GVC brand is widely recognized as a leader in providing valve and flow control solutions for the energy , and oil and gas industries’ for a general all around great product and a fair price.
V- Port Ball Valve – A V-port ball valve has either a “V” shaped ball or a “V” shaped seat. This type of valve also is known as a control valve in which the flow velocities need to be controlled / regulated as required per the application.
In closing Global Valve & Controls ball valves can be used in a variety of applications and markets, such as pipeline transmission, pig launchers, storage facilities, pulp and paper facilities , food and beverage , gas processing , industrial, and many more . Troy Richard, founder of Global Valve & Controls (GVC) explains that ball valves provide reliable leak protection and fugitive emissions concerns. Ball valves can be open and close quickly in which saves time and money on all automation packages.

When I first started working at a valve company I had to research quite a bit on what valves were and what they were used for. Yes, I was a newbie. There is so much information on the web today that I could go on and on but focusing on one of the products that the company is most known for will cut down my blog from about 10 pages to a paragraph. (Plus, who wants to read 10 pages!!?)
Trunnion ball valves are the “Big guys”, at our warehouse and I was very intrigued by the size of them! The sizes can range anywhere from 2INCH to 48INCH. Working at the company, I had to learn my way around the valves. At first it was over whelming because not all valves are made the same. I created a list of 5 questions to help me.
1.What is the ANSI class?
2.What is the material?
3.What is the size of the valve?
4.What are the end connections of the valve?
5.Are you looking for Reduced port or Full port?
Understanding what the valve is used for helped me better understand what exactly the customer was wanting. I will not say that I am an expert in no way on valves but working in the environment has really made me appreciate what valves are used for and how we use them in our everyday lives.
My curiosity spiked when I began reading how these trunnion ball valves were used. Having lived in Texas, (O&G state), I know pipelines are the most common areas where one would see these kinds of valves. I of course got to my computer and started researching more about pipelines, which is another blog to come. I will however include that pipelines do not just carry oil, but a wide variety of liquids and gases. An interesting little fact I picked up along the way is that there used to be a vodka pipeline, now how crazy is that!
In the world of valves there is always so many to choose from. Flanged ball valves, Threaded ball valves and the list goes on! Other things you must know when calling in for a quote is the size, trim, material, reduced or full port of the valve and most importantly what the valve will be used for. When you have finally decided that you need a flanged ball valve for your application, you will need to decide if you will want a 1, 2 or 3 piece valve. You will make a decision based on cost, maintenance and if it will need to be automated.
First, lets take a look at a one piece flanged ball valve. Contrary to what others say, a 1 piece design ball valve or unibodies are not always the cheapest and you can automate any flanged ball valve with a mounting pad. These valves are not repairable so if one breaks you will need to replace the whole valve which is time and money. If you are looking into a 1 piece flanged ball valve, be sure to check out our Series FS or http://gvcintl.com/files/GVC%20Series%20FS.2011.pdf
A 2 piece and a 3 piece ball valve was definitely designed with maintenance in mind as it can be easily cleaned. The biggest difference between the two is that the 3 piece can be taken out of line without affecting the two end caps while the 2 piece can not. As far as cost, a 3 piece is more expensive up front but in the long run it could be a wiser choice as the seats and seals are replaceable and with a 2 piece you will need to replace the valve entirely if there are any issues. If you are looking for a 2 piece flanged ball valve, take a look at our Series CFS, FS600, or
Stainless steel ball valves are definitely one of the popular materials that many people buy. They are perfect for the food and beverage industry, agriculture as well as the pulp and paper industries. The reason behind this is because stainless steel does not corrode and when dealing with food which we consume you do not want your machines corroding. White it is true that stainless steel (SS) does not easily corrode or rust, it really depends on the oxygen level in atmosphere. For example, if it is a poor air circulation environment, depending on the grade of the SS valves the valves may or may not corrode. Therefore, it is always important when dealing in such circumstances to get a high grade type of SS valve.
The material stainless steel is not to be confused with carbon steel as carbon steel will rust at one point in its life. The difference between the two metals is the amount of chromium present. Stainless steel’s resistance to corrosion and staining, low maintenance, and familiar lustre make it an ideal material for many applications. The alloy is milled into coils, sheets, plates, bars, wire, and tubing to be used in cookware, cutlery, household hardware, surgical instruments, major appliances. These are examples of a few items one may be familiar with.
It is very important to know which grade of SS you need for your application as stated above if the grade is low, it will not last or you will have problems later down the road. Therefore, always consult with the manufacturer before buying. Global Valve and Controls can provide you with 316SS, 317SS and 304SS just to name a few. There are many different grades and one may not know that 304 is not to be used in the presence of sulfuric acid.
Purchasing valves can be a major headache for some. For starters, one must know what kind of valve they are in need of and whether or not it fits their application. The following questions should be asked in order to find the proper valve;
– What is the media?
– What is the temperature?
– What is the pressure?
– Is it an open or closed position?
From there, the manufacturer will have a better idea of what the end user is really looking for. Many times, the manufacturer will find an error and will need more information to provide the best valve.
Once the valve is picked up and has landed in the end users hands, maintaining the valve is the next step. Many people think that once a valve has arrived it is placed in line right away, but this is not the case. Many steps are taken to insure the end user has received the order as they will have many shipments in one day. Step such as;
– Ensure the valve, actuation and valve control accessories bill of materials matches the end user’s specification sheet.
– The exterior of the valve and components checked to make sure it was not damaged in transportation
– Ensure the valve process connections are covered (See article for more details)
Once the valve is “in line”, “stroking the valves and applying general-purpose lubrication at least once a month provides longer-term benefits in the functioning of in line valves”.
“The incidence of leaking valves immediately following installation occurs too often, with the blame placed on the valve and its manufacture instead of the end user’s misapplication.” Making sure to follow policy and procedure and taking preventative steps will help get the right valve for the right job without any problems.
Theory: Cold weather dictates a different type of lubricant to avoid seizure and promote proper function inside the gear housing.
Global Valve and Controls states, “in order to have a proper functioning valve it is necessary to use the correct grease inside the gear housing.”
In a case study where non-cold rated grease is applied to a valve that is heading to Wyoming, where the weather can be frigid seven months out of the year; the likelihood of the valve seizing becomes increased and the average lifespan potential will decrease.
Aftermath: It is a wise decision to consider the environment that your purchased valve will be applied to. With Global Valve and Controls, these are questions we ask our customers to protect their investment in order to increase the longevity of their valve; like a vehicle, it is important to use the recommended lubrications and oils to ensure proper performance. Valves are the same way. Moving parts need the correct lubrication to operate proficiently.
Fact: Materials such as grease or oil, are affected greatly by weather, hot and cold. However, lubricants can be engineered to withstand various environments by being structured to hold their viscosity.
Let’s take a look at the CFS valves. What are they? What are they used for? What sizes are available, materials, I promise all your questions will be answered right here, and if they are not, well now you know who to contact.
The CFS is one of our widely used ball valves; it is used in a wide variety of industries such as oil/gas, petrochemical , pulp and paper , skid package equipment. If you are wondering what is so special about this particular valve. I would say it is considered a high quality, low maintenance ball valve and the price is very competitive compared to other brands. Take a look at some quick facts:
Sizes 2″ – 12″ ANSI Class 150-300
2-Piece Body Floating Flanged Design, Full, or Reduced Port
Raised Face and Ring Type Joint Ends (RTJ)
Self-cleaning, Leak Tight Slotted Seat Design
NACE MR0175 Approved
Design and Tested to API 6D
Fire Tested according to API 607 Standards
Floating Ball Design prevents Cavity Pressure Build-up while the Valve is open
The valve has many components that you can choose from when ordering, thus it is always important to know the media or application the valve will be used in. Knowing what end connections you need is very crucial. Not all applications can accommodate.
Raised Face (Flanged) Connections
Ring Type Joint (Flanged) Connections
Socket Weld Ends
Occasionally Butt Weld (Not Standard Production End Connection)
Fact: Did you know that Flanged End Connections are known for being easy to apply to your project?
You may wonder what the difference is between Flanged and Threaded Ends. Flanged Valves feature more bolts, resulting in less tightening, in contrast to Threaded End Connections which need more tightening. Flanged Ends overall can be used for any type of Valve, i.e. Gate, Globe, Ball, or Check. When you have a Threaded End, ultimately you will be working with a Low Pressure type situation. GVC offers Valves with Threaded End connections and can be modified to Socket Weld or Socket Weld x Threaded if need be.
Socket Weld End Connections are commonly used on Stainless Steel or Carbon Steel Valves. When you have a higher temperature and pressure rating you would want to turn to the SW Connection. GVC offers SW Ends and features their leak free seal.
Last but not least, the RTJ and Butt Weld End Connections: GVC stocks majority RTJ End Valves opposed to Butt Weld End Valves. Butt weld end valves are applied to most applications where a higher grade of steel, temperature and pressure is needed. An Engineer from an article I found states, “RTJ Valves have grooves cut into their faces in which they obtain steel Ring Gaskets. They seal when tightened bolts compress the gasket between the Flanges into the grooves, deforming the gasket to make contact inside the grooves, thus creating a metal to metal seal.” Each valve end is beveled to match with the thickness and bevel on the pipe.
Can you guess what the end connections in the picture are?
