The Ultimate Cheat Sheet on Fisher® Control Valves
Everything you wanted to know about remanufactured valves but were too afraid to ask
You’ve probably heard of remanufactured Fisher control valves, but what exactly are they and what are their benefits? That’s what this guide is here to answer. Remanufactured valves can:
- Save you up to 70% on costs
- Cut your lead times down to 2-3 weeks
- Provide a reliable solution for your process control needs
In today’s competitive market, plant and oilfield operators are looking for creative ways to cut costs. Because of that, there is a growing trend of purchasing remanufactured control valves and process control instrumentation. On top of the obvious cost benefits of remanufactured equipment, remanufactured equipment is also more environmentally friendly. Some consumers worry about reliability, but Automation Service can remanufacture Fisher control valves with a remarkable amount of skill, precision, and quality. Despite the benefits, there is still a lot of confusion in the marketplace about remanufactured valves. Continue reading to learn more about control valves and what remanufactured equipment can do for you.
Types of Valves
As the saying goes, control valves control; shut off valves shut off. And neither one does the other’s job very well.
An automatic control valve opens and closes to increase or decrease the flow of process fluid through it to keep a measured process variable at its desired setting. These types of valves are extremely important and perform the job of controlling a process very well. However, they don’t always close tightly enough to completely shut off the flow of process. But should they be expected to? Absolutely not. Learn more about allowable leakage rates on our blog.

Control Valve Sizing
Because we can produce remanufactured control valves with such precision and quality, they represent a viable alternative to new equipment. But automatic control valves are not one-size-fits-all. Accurate sizing and proper specification are essential to providing the right size and type of automatic control valve assembly to meet the application’s requirements. One thing to keep in mind is the shutoff classification of your valve. Do you need class two, three, four, five, or six? It’s important to know what your application requires when you order a remanufactured control valve.
But even a properly sized control valve won’t do its job if the actuator moving it isn’t properly sized as well. To operate the valve properly, the actuator has to overcome and balance the force working against the movement of the valve. Another often missed factor is control valve bench set. This is an often-misunderstood point of confusion, but not understanding it can set you up for a mis-sized actuator and spring. Visit our blog to read more about bench set requirements.
If you need assistance sizing or specifying a control valve assembly for your application, contact Automation Service. Our staff of engineers is here to help.
Control Valve Troubleshooting and Maintenance
One simple thing you can do to extend the life of your control valves is routine valve packing maintenance. Other areas that may require routine maintenance are soft goods, trim, the actuator cylinder, valve positioner, and air set or air supply regulator. If you have a pneumatically actuated valve, using a filter regulator can also help extend the life of your pneumatic instrumentation. Watch our video to learn more.
But sometimes even well-maintained valves will run into problems. When that happens, you may need to try some basic troubleshooting. If you would like assistance, give us a call. Our staff of product experts is here to help! You can also check out our video library for helpful tips, like how to adjust the actuator orientation for an E-body sliding stem control valve.
Testing Remanufactured Fisher Control Valves
Because of the increasing popularity of remanufactured automatic control valves, manufacturers and users are prioritizing reliability. You need to know that the control valves you purchase will perform their expected tasks with accuracy, efficiency, and reliability. That’s why proper quality testing is so important to Automation Service. Without complete and proper testing, the valve may experience systematic failures. Each remanufactured control valve we sell is validated by rigorous testing, including hydrostatic testing and seat leakage testing.
What does this mean for your plant? It’s critical that you understand what you are buying when you purchase a remanufactured valve and make sure that it is up to the required standards. That’s why when you purchase a valve from Automation Service, you will receive a control valve test & calibration card with your order to provide you with critical test results. Watch our video to learn more about valve cards.
