Unrivalled spherical grinding capability

Cost saving refurbishment service

Improved performance & longevity

Established in 1979, our unique grinding capability ensures the perfect sphericality of a ball valve, such that it will seal in any position, through the opening and closing process.

This unrivalled capability can be applied to both new ball valves, as well as the refurbishment of balls that have failed during operation. Our capability can significantly increase the product life and performance of a ball valve system, relieving end users of the heavy costs associated with downtime or ball replacement.

About Martract

Spherical Grinding

Ensuring the perfect sphericality of a ball valve, such that it will seal in any position, at any orientation through the opening and closing process. The ability to grind a selection of material from carbon steels, to stainless and high performance exotic alloys through to tungsten and chrome carbides.

Ball Valve Refurbishment

Our unrivalled refurbishment service can be applied to any type of valve, including ball valves, gate valves and butterfly valves. With time being a critical aspect of refurbishment to minimize plant downtime we offer some of the fastest refurbishment lead times available.

Flat Lapping

Optical Flatness to 1 light band and Surface finish requirements to many components and materials

Premium Polished

Finishes

Guaranteed surface finish to a maximum of four micro inches if required.

Lapping Supplies

Machine & Consumables (Diamond/Boron and Silicon Carbide supplies)

Capability

Do you know that the perfect sphericality of a ball valve is possible?

Do you know that this capability can be applied to the refurbishment of ball valves that have failed during operation?

We can refurbish failed ball valves for significantly less than the cost of seeking a replacement. And the potential cost savings don’t end there.

Ball valve failure is not uncommon. The resulting downtime and ball replacement incurs heavy costs that could well be significantly reduced or avoided.
We can refurbish failed ball valves for a cost that is, on average, 40% less than a the cost of a replacement
What about turnaround? In most cases, we can refurbish a failed ball in less than half the time it would take to manufacture a replacement
The performance and often improved longevity of a refurbished ball also provides end users with further cost saving benefits.

In many cases, ball valves and seats refurbished by Martract will improve performance due to improved roundness, concentricity and surface finish than the original manufacturers balls and seats.
As well as performance, our capability will significantly increase the life of a valve ball system with the improved tolerances and the ability to integrate hard faced coatings (Tungsten or Chrome Carbides)
