Valve Traceability

If you have ever purchased a valve from us then you already know we don’t just sell you a valve but provide you life long service and 24/7 technical support if any issues arise. All our valves 2″ and up come with valve traceability. This ensures us that we are able to track the valve where ever it may go. The valves have a special serial numbers that allows us to trace them back to the manufacturer date and all components that are used. A few questions that we get from our clients regarding valve traceability are;

Do you have to trace the valves often?

Not very often. Sometimes a customer will need parts and will send the serial number or they might have lost the Material Test Results and will send the serial number which allows us to look it up.

Why is it important to be able to trace a valve? 

It is important so you can trace the history of the valve from the time it was manufactured and all the components to when it was shipped, received and sold. We can trace the whole history. If we did not have valve traceability then It would be impossible to know whether the valves are manufacturerd to the right standard and are able to sustain the pressure that is needed.

As you may know the valves industry is becoming more and more competitive and having a valve traceability system is one way we stand out as a manufacturer. At Global Valve and Controls, our valves of course are NOT from China which is important to note as there are many companies that have their products shipped from the Middle East, India and China and there is no way to track where the parts are coming from. This is why we make sure to be one of the few valve manufactures that provide this service and be API 6D certified. Please see our website for certification https://www.globalvalveandcontrols.com/certifications.html

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 seats when the valve has the Double Block and Bleed (DBB) feature.”

You may find Double Block and Bleed valves in many types of industries, including; Gas and Liquid pipelines, Production, Processing Oil and Gas, and more. This feature ensures zero leakage which is why they are popular in pipelines. 

Do not be confused with Double Isolation Bleed which according to API means, “API 6D defines a Double Isolation & Bleed Valve (DIB) as a “single valve with two seating surfaces, each of which, in the closed position, provides a seal against pressure from a single source, with a means of venting/bleeding the cavity between the seating surfaces. The note adds that this feature can be provided in one or in both directions.”
