Facts about Threaded End Ball Valves

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.

GVC offers:

  • Raised Face (Flanged) Connections
  • Ring Type Joint (Flanged) Connections
  • Threaded Ends
  • 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?

Making Use of Steel Ball Valves

When it comes to infrastructure, we can really name a lot of companies which are getting into it and one of the most in demand services anywhere today is plumbing. Without plumbing, people would always have a ruin day due to an inadequacy of water. More than that, when we are also going to talk about plumbing, we also need to consider the things that they mostly use and one of which are those valves that are useful in order to make a job successful. If you are among the plumbers, you will surely look for the most durable and top-quality kind of valve, and in such case, the use of steel ball valves should be taken account.

There are now plenty of manufacturing companies who had study hard in order to make the best valve to use in any sorts of plumbing activity and good thing was, Global Valve and Controls had able to establish the perfect valve to be used in any sorts of plumbing constructions. Steel ball valves are among their recent valves being made which has been establish through the finest technological method and had able to pass various evaluations from experts as well. With these steel ball valves, you can really have the guarantee that this would last long despite the fact that it is being use constantly.

Global Valve and Controls had undergone careful study in order to perfectly design the right valves to be use in all sorts of plumbing construction. GVC’s have their own technical support team who see to it that all steel ball valves are of top quality and will even provide you with best function. You can now start buying these steel ball valves since these are now available in all markets in your place.

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.
