Fittings machining

The valve market is closely linked to the piping market and its connections. The ends of the pipes  have very different shapes and dimensions, in order to adapt to the needs of each application. It is often necessary to find a good solution for pipe machining.

Reduced lead times for valve body machining

Today our customers find themselves in a very demanding and unstable industrial environment. In this context, the demanded needs often require very short response times. The valves sector is aimed at markets such as OIL&GAS, Nuclear, Desalination, Petrochemical, Mining... among others. These markets cover very diverse applications but in all of them there is a high demand to respond quickly to urgent needs. ARRI, aware of this market evolution, has a wide internal development in the clamping systems to have an immediate reaction. The valve body machining service (among other components) offered by ARRI must necessarily be adapted to different special geometries depending on the requirements of each project. With in-house designed modular clamping systems, ARRI is able to clamp all kinds of parts with special geometries within 24 hours.

We solve the problems of wedge fitting in the cast gate valve bodies

We solve wedge fitting problems in gate bodies.

Usually in cast gate bodies where the guides are part of the casting, it is detected that the geometry of the guides is irregular. This is not normally a surface where machining is foreseen, but in the assembly process when the wedge is placed, problems are generated. These problems result in the need to rework the affected surfaces of the guide with the technical difficulty that this implies and the delay due to the paralyzation of the valve assembly, in addition to the extra costs derived from this process.
