Go Tornados!!!

This year we decided to sponsor the Tornado soccer team which is part of Fun Fair Positive Sports or FFPS. Our very own D’Aunna Goins son is part of that team. In case you have not heard of this group, FFPS is a non-profit organization which promotes noncompetitive soccer in a fun, safe and positive environment. This past weekend the Tornados have played against the Creepers, Rangers and the Jaguars. We are very excited to learn that the Tornados scored victory and won all the games!…

An Inside Story: Working in Outside Sales at GVC

Has anybody ever asked you if you would be interested in working in Outside sales? You might be dreading it as going door to door isn’t a dream job, or Is it?  While I do know people like that, I am here to tell you that not all outside sales are created equal. I had the pleasure of speaking to one of GVCs Outside sales ladies and she had the pleasure of telling me what actually happens when she does get a chance to go…

Gearbox installation on a Trunnion Ball Valve

Gearbox installation on a Trunnion Ball Valve Installing a gear box on a Trunnion ball valve is no easy task. In fact, if you want to learn be ready to get your hands messy. It is recommended to buy some gloves that are suitable to wear for the lubrication process. Remember to always consult the manufacturer first. Start by generously lubricating the stem of the valve. We use an industrial high-performance grease that works with the same temperature ratings as our valve. Apply grease to…

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 Through Conduit Gate Valve

One of our newest valves on the market is the Through conduit gate valve. Sometimes also referred to as Thru conduit. It is used for pipe pigging, but can be found more in “pipelines of subterranean heat steam, petroleum, natural gas production, transmission, and storage” The GVC Thru conduit gate valve is API 6D certified and has Double Block and Bleed capabilities. We offer these valves in 2” all the way through 36”. Many companies in the petrochemical industry prefer to use the Thru conduit…

Double Block and Bleed Valves

The Double Block and Bleed is a special feature that you can find among our Trunnion Ball Valves and Expanding Gate Valves. The idea of having DBB was first created by engineers. According our our ValveMD, “The DBB feature of the valve or valves is the ability to segregate two pressure sources and to bleed/vent pressure in the void between the two sealing elements (blocks). The bleed may be in the pipework/pipeline when two valves are used, or in the valve body between the two…

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…

Cryogenic Ball Valves

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…

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.   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,…

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…
