What makes GVCINTl the preferred Valve Manufacturer?

Have you heard the saying, “you pay for what you get”? Well, when it comes to buying a valve, quality does matter. Imagine purchasing a valve for a pipeline project and of course you as the buyer would like to save the company money, unfortunately not all valves are created equal. We as a valve manufacturer provide only the highest quality material for our valves which means not only are you provided with the best quality but also the best price for all your flow control products.

What makes GVC the best valve manufacture? Hard work goes into making a valve, and it is not just the high-quality materials but also the dedication and devotion of our employees. All our valves are inspected not once but three times before sending it out. Once you purchase a valve from us, our valve technicians provide 24 hours support every step of the way. It is always a good idea to purchase API 6D quality products because of the high standards to reduce emissions and other environmental factors. One thing to remember is when purchasing a GVC valve, you are guaranteed that the products you purchase will last longer in severe and critical applications. GVC valves will exceed all your expectations. Go ahead and take the GVC Challenge.

Please see our website for more information on API 6D certification.

 

 

Hydrostatic shell testing

Many times a client of ours will ask us to do additional testing to the valve/s before they purchase. One of the tests that is asked for is called hydrostatic shell testing and because we have our certification for API 6D such a test like this is no problem at all. Hydrostatic shell testing means that the shell, or the body of the valve will go through a pressure test. All valves MUST be hydrostatic ( WATER) shell tested to verify the valve can handle the maximum pressure it was built and designed for.  What you see in the video below is a hydrostatic test pressure, usually 1½ times the rated working pressure is applied to an assembled valve to verify the structural integrity of the pressure containing parts. Pipeline valves commonly go through these types of tests to ensure there are no leaks. Check out our Youtube page and you will see one of our API 6D, Trunnion ball valves going though the hydrostatic test and the test will continue for 4 hours. We stride for customer satisfaction and do not have any complaints. Contact us for more info www.gvcintl.com

 

What does it mean to be API certified?

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. 

 

 

Types of Ball Valves

Types of ball valves :

 

Different types of bores for ball valves – full port, reduce port and V-port. These three types have different constructions and purposes.

 

  1. 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.
  2. 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.
  3. 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.

Pipelines Ball Valves: An inside story

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!

What are Actuators?

What are actuators?

What are actuators and how do they work? There are four types of actuators that are used today.  The most commonly used in this industry are the Pneumatic and Hydraulic actuator.

hydraulic actuator consist of a cylinder or fluid motor that uses hydraulic power to facilitate mechanical operation. The mechanical motion gives an output in terms of linear, rotary or oscillatory motion. Because liquid cannot be compressed, a hydraulic actuator can exert considerable force, but is limited in acceleration and speed.

pneumatic actuator converts energy formed by compressed air at high pressure into either linear or rotary motion. Pneumatic energy is desirable for main engine controls because it can quickly respond in starting and stopping as the power source does not need to be stored in reserve for operation.

You may wonder what this means in English? Well, in simpler terms; the main difference between the two is that pneumatic actuators use air to transmit force while a hydraulic actuator will use liquid to transmit force. Depending on the media of your project will depend on what kind of actuator you will need.

This picture shows an example of what a pneumatic actuator might look like with a ball valve. A Pneumatic scotch yoke Automation package along with our ANSI 1500 Trunnion Ball Valve going for Natural gas service.
