Many of the valves end up in the scrapyard. Choosing to recondition can save you up to 50% or more compared to buying new equipment.
Reconditioning can reduce the need for costly modifications to existing pipework that new equipment might necessitate.
Our efficient processes ensure minimal disruption to your operations. Timing is depends on the size and condition.
Maximise your investment's value by extending the life of your valves. Regular maintenance and repair on expensive valves.
We can organise the collection and delivery of your valve. We have experience shipping nationally and internationally..
Avoid the valve having to be scraped and recycled. This is an energy-intensive process and avoiding the costs on materials.
Valve brands, types and sizes.
Refurbishing industrial valves involves working with a wide spectrum of brands and makes, each with unique construction features and performance criteria. Well-known names in the field include Bailey, Crane, Hopkinson, Mack, Klinger, Saunders, Spirax Sarco, among others.
These manufacturers produce a variety of valve types—such as gate, globe, check, ball, butterfly, and safety valves—each with specific tolerances, sealing methods, and material compositions. Effective reconditioning requires familiarity with the engineering standards of each brand, as well as the capability to source or reproduce parts that meet original design specifications.
Technicians must be adaptable and experienced in handling both legacy and modern valve designs to restore functionality and ensure reliable performance after overhaul.
