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.

1, 2 or 3 piece Flanged Ball Valves

Flanged Ball Valves

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

Keeping your valves in check

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.

20 RP VS 20 FP

Have you ever wondered what the difference of a 20 Reduced Port Ball Valve and a 20 Full Port Ball Valve?What do you think the differences are after reviewing the chart above?

Observers below:

–   Operations Director states, “Well the cost is a big one, however, the CV Factor changes. Although, the port also changes, but a Reduced Port constricts the flow while the Full Port allows the flow to just flow.”

–   Vice President of Sales & Marketing states, “One is full port and the other is reduced; however, a full port sizes go up to ¾”

–   Account Executive-Inside Sales Account Manager states, “One is full port and the other is standard port, however 20RP’s are considered full port up to ¾” (Water, Oil & Gas Applications. And 20FP’s are a seal welded design.”

–   Account Executive-Inside Sales Account Manager states, “20 RP’s are considered full port up to 3/4”

 

The actual differences are: The CV Factor, how one port functions as compared to the other port, Full Port are a Seal Welded Design, Weight, Length, as well as Height
