How can you get a valve positioner to work in excessive vibration – or other unsafe or poor locations?

At times, we have valve positioner applications that are affected by excessive vibration, temperatures, radiation, magnetic influence, and unsafe and/or poor locations. Addressing the root cause of the issue can be timely, expensive and sometimes deemed impossible by plant management.At one power plant, I remember a situation where they had placed the valve too close to the boiler. Because of its proximity to the boiler, employees were hesitant to work on the valve. To make matters worse, the va ...

Siemens PS2 - The Cost of Air-1

How much does plant air cost you?

Have you ever wondered how to quantify something you can’t see? How about equating that something to dollars? What if that “something” was plant air and your valve positioner was consuming a lot of it? How do you quantify that, and is it even worth your time?In short, yes, it IS worth it!  A few years back, Dick Colony showed us how getting a handle on the cost of air saved one customer $600,000. You can read it here.How do I know my cost of air?It’s now easier to determine with the Siemens Cost ...

Product Spotlight – Integral Volume Booster for the SIPART PS2

Continual improvement is what we strive for at Siemens. Many times, design improvement ideas come from the people that use our products the most, our customers. With that in mind, we’ve developed a solution to answer the need for a simpler volume booster design.Siemens’ Integral Volume Booster (IVB) will provide users with the high flow requirements needed to move large valves while simplifying the installation process. The IVB connects to the SIPART PS2 and directs a high volume air supply to t ...

Got Gas?

In the oil & gas industry, there are instances where you would use natural gas to move control valves.  Why spend money on a compressor for producing instrument air and additional electricity costs when you have ample natural gas available?  There are issues, however, in using the gas for these applications, particularly if the valve is being controlled by an electronic signal. Gas isn’t always easy.The most important question you can ask yourself is:  what is in the gas?  Gas can be great, ...

How do you save $600,000?

A large tobacco company was about to spend in excess of $600K for an additional utility building compressor. The facility air system was failing to meet pressure requirements based on the overall demand of the existing system with 2,500 positioners. By explaining key benefits of the PS2 valve positioner (click here to see for the benefits for yourself) and running a few tests, we were able to give them the air (and dollar!) savings needed to skip the purchase of a new compressor. Could you be in ...
