The eyes and ears to your valve assembly

Control valves can be fickle pieces of equipment. If we take a step back and say, “What are we asking the control valve to do?” The answer is: we are asking this piece of mechanical equipment to provide the same type of precise movement time and time again. There are many factors working against this goal including tight tolerances in the valve assembly, mechanical wear, system issues, mis-sized valves/actuators and even installation/operational errors. Over time, many of these issues compound a ...

How much water is used in the oil and gas market?

Quick quiz: How much water is needed to drill and frack a horizontal well?a) 25,000 gallonsb) 250,000 gallonsc) 2,500,000 gallonsIt may seem crazy but each new well requires over 2.5 million gallons of water for completion. Not only that, besides the water needed for drilling and fracking, industry experts have found that for every one barrel of oil produced, over seven and a half barrels of water are also produced. For the production of one million cubic feet of natural gas, over 260 barrels of ...

Valve Performance Test Picture

What are valve positioner diagnostics and how are they important to your valve?

Industrial plants are being tasked with reducing costs and increasing production. To achieve this, they must exploit plant efficiencies while simultaneously reducing their workforce. This forces plants to rely on their suppliers for the know-how solutions and advice to accomplish these tasks.Quickly realizing that it’s not just about cutting costs but maximizing operational efficiencies, plants that are thriving during this time are choosing equipment and suppliers that offer value.The valve and ...

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, ...



Siemens' PS2  intelligent positioner provides a flexible  solution for all types of control valves, incorporating intelligent  valve  diagnostics and communications via HART, Profibus PA or Foundation Fieldbus.  Equipped with standard comprehensive diagnostic functions, the PS2 continuously checks the actuator and valve, so it will provide advanced failure warnings during operations.
