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…

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…

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…

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.…
