Remanufactured
Fisher Valves
Modern remanufacturing processes reclaim used Fisher valves and rebuild them to original equipment manufacturer (OEM) specifications—often at a fraction of the cost and with faster delivery. This guide explains what remanufactured Fisher valves are, how they are produced, the benefits of choosing them, and the range of control valves available.

Factory‑Level Reliability and Quality
Rigorous Testing
Automation Service subjects every valve to hydrostatic testing and seat‑leak testing to ANSI/ISA standards. Valve Sales Inc. describes additional tests actuator spring testing, Niton™ XL2 positive material identification and optional BenchMark™ control valve diagnostics to verify trim materials and performance. Emerson’s ENCORE program uses OEM checklists and quality control at every step to ensure the valve meets dimensional tolerances and material specifications.
OEM Specifications
Automation Service rebuilds valves using OEM drawings and the most current engineering updates; body wall thickness is verified to ASME B16.34 standards. Valve Sales Inc. highlights that new soft goods (gaskets, seals, O‑rings) are installed and worn parts are relapped or replaced
Documentation and Warranties
Each Automation Service valve is accompanied by a test & calibration card summarizing the results and is covered by a two‑year warranty from the installation date. This warranty matches or exceeds many OEM warranties and is echoed by competitors such as Valve Sales Inc. and MSEC

How Remanufactured Fisher Valves are Rebuilt
The remanufacturing process begins with core collection and inspection. Used control valves are disassembled and cleaned. Valve bodies and bonnets are inspected for corrosion or cracks. Experienced technicians then rebuild the valve according to OEM drawings and updated specifications. Key steps include:
- Dimensional checks and machining. Body wall thickness is measured to ensure compliance with ASME B16.34. Surfaces are machined to restore gasket and seat faces
- Component replacement. Soft goods (seals, gaskets and packing) are replaced with new materials. Trim components—plugs, seats or V‑balls—are relapped or replaced to achieve proper shut‑off
- Reassembly and calibration. Actuators are inspected and springs tested; accessories such as positioners, air sets and I/P transducers are repaired or replaced
- Testing. Every valve undergoes hydrostatic testing to ensure the body is leak‑tight, and seat leakage testing to verify proper shut‑off class. Optional tests include Positive Material Identification (PMI) using X‑ray fluorescence to verify alloys, Benchmark™ diagnostics to measure travel, response and hysteresis, ultrasonic thickness testing, and actuator spring testing.
Painting and documentation. After passing all tests, the valve is painted and labelled. A calibration card summarizes the test results and assembly details.
Benefits Compared to New Valves
Cost and budget flexibility
- Capital expenditure reduction. New Fisher control valves are expensive; remanufactured alternatives can save 30–70%.
- Reduced total cost of ownership. High‑quality remanufactured valves often include longer warranties than new products (two years vs. one year for some new Foxboro controllers). Their shorter lead times reduce downtime costs.
Equivalent performance
- Built to OEM tolerances. Emerson’s ENCORE program emphasises that remanufactured Fisher valves meet the same dimensional tolerances and material specifications as new valves, backed by a factory warranty.
- Certified testing. Both Automation Service and Valve Sales Inc. test to ANSI/ISA standards, ensuring mechanical integrity and tight shut‑off.
- Customised trim and materials. Customers can specify body materials (e.g., carbon steel, stainless steel, chrome‑moly, alloy 20, etc.) and choose special trims for corrosive or abrasive services
Sustainability
- Recycling reduces waste. Remanufacturing extends the useful life of valve bodies and actuators, diverting them from scrap. Automation Service runs a reclamation program where clients earn credits for returning used controls.
- Environmental stewardship. MSEC notes that remanufactured valves are more environmentally friendly because they reuse materials and require less energy to produce
Selecting and Sizing Remanufactured Control Valves
Proper sizing and specification are essential for achieving accurate control and avoiding premature wear. Factors to consider include:
- Process conditions. Know the fluid (liquid, gas, slurry), operating pressure, temperature and flow range. Determine whether you need on–off service or precise throttling.
- Shut‑off class. Control valves are available in Class II–VI shut‑off ratings. Applications requiring tight closure (e.g., steam isolation) may need Class V or VI.
- Valve/actuator sizing. A properly sized actuator must generate enough force to move the plug or ball under worst‑case conditions. Consider the bench set and spring range when selecting actuators.
- Materials and trim. Choose body and trim materials compatible with the process. For corrosive or erosive fluids, specify alloy trims (e.g., Alloy 6 or ceramic coatings) and bearing materials like PEEK.
- Accessories. Positioners, I/P transducers and air sets can improve accuracy. Ensure accessories are remanufactured and tested or specify new OEM replacements.
Automation Service’s engineers can assist with sizing and specification; other providers such as MSEC also offer personalized product selection
Frequently asked questions
Are remanufactured valves as reliable as new ones? Yes—when rebuilt by reputable suppliers and tested according to ANSI/ISA standards, remanufactured valves can match the performance of new equipment.
