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

Lubricants for Your Valves’ Gearbox

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.

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.

Global Valve and Controls strive to provide earth friendly options, especially the containment of fugitive emissions being released in the earth’s atmosphere.  Over 44% of a plant’s expense, is due to leaking valves and the replacement of them because of old technology, such as the Chevron design.  GVC has a new technology to lower this expense by a substanial decreased cost of ownership.

GVC has been manufacturing an accessory, the Media Containment Bonnet, since 2004.  The MCB is unique because of the installation, maintenace and application, as an option to our ball valves. The following highlighted reasons to incluse this accessory for $300 – $500.00 at time of purchase of the ball valve series are as follows:
  • Increases the longevity of the ball valve.  A standard increased life expectancy of a leaking ball valve, with the GVC MCB application, is an extra three years.
  • No down time due to the shut down of a plant or pipeline because of  the removal of a leaking valve. Within 10 mins, the MCB is installed with no tools other than a wrench is necessary.
