Hi all,
There is any guidelines or check lists that could be used for vigilance on control valve proactive maintence, so that in service control valves can be kept in top performance.
Things like leaking packing, positioner feedback arms and so on are usual ones, but is there other items to look out for?
Thanks
Gerard
Gerard, Absolutely, there is well documented guidelines for maintenance of control valve "in service Diagnostics" using microprocessor based Digital Valve Controller to provide improved performance and higher plant availability. You can download the document by clicking on the PDF link below. I can also send them to you via email. Can you please send me your email address to send the details?
