Whether you carry out your own control valve maintenance or use a third party, the design of a control valve will influence your strategy and budget. To stay one step-ahead of unexpected maintenance challenges, I’ve put together my top key takeaways when it comes to control valves:
Do your control valves look a bit worse for wear? Perhaps even under performing? If you’re looking at replacing your control valves, but you want to ensure that you can get your system back into service as quickly as possible so that you can get on with your day, then you need quick delivery. Fortunately, I can help you with that as Spirax can deliver within 48 hours on a large selection of control valves. Even better for you, the valves leave the factory already pre-commissioned for applications letting you do a quick installation.
In my role as Controls Specialist, I’ve been to many sites and you would be surprised (or maybe not?) at how many control valves there are out there in plants where the control valves aren’t actually the best fit for the process conditions. Make your life easier and help yourself by asking whether the materials have been chosen with the process conditions in mind. Is the right grade of stainless steel being used for the control valve internals? Will this stand up to the potential for corrosion and erosion?
On the surface of it a control valve may be advertised as maintainable, in my experience however this is not always the case. For instance, control valves with screwed in seats are notoriously difficult to maintain with the seat sometimes being impossible to remove which can be extremely frustrating as it leaves you with the options to either live with an under performing control valve which is of no benefit to anybody or take the unenviable route of buying a new one.
Maintenance shouldn’t be a massive headache as the design of the control valve should be such that maintenance is straightforward and doesn’t significantly impact on process downtime, which as we both know can cause more than just a headache!

A win-win situation: Increase productivity and help the environment
Process managers could be making improvements to increase efficiency and product quality by paying closer attention to the specification of controls systems used within their facilities – that’s the current message from Spirax Sarco’s National Controls Specialist, Darren Silverthorn.
