In ARRI Machining, we are specialists in machining all types of valves: gate valves, ball valves, globe valves, check valves, plug valves, butterfly valves... Trevisan machining machines have allowed us to machine these different types of valves and parts in other materials and of various sizes, even machining parts up to Ø2400mm by turning and 25t, thanks to the Trevisan DS 1200 model.

Large valves are used in the oil & gas and other markets because they control the flow of fluids at high pressures and temperatures. These valves are essential for safe and efficient oil and gas production, transportation and storage operations.

ARRI Machining closely aligns the valve market with the pipe and fittings market. We specialise in the machining of valves and the machining of high-specification fittings.

At Talleres Mecánicos Arri S.Coop. we continue to work with a management system based on continuous improvement. In our commitment to satisfy the needs of our customers, we continue to rely on process management based on the ISO 9001:2015 standard.  Our certification under this standard has been extended in the last recertification audit for the period 2022-2025.

We are pleased to announce the latest addition to our Trevisan machinery fleet, the Trevisan DS450/130C. With this new investment, Arri covers a range of dimensions that it did not have until now. We currently dispose the full range of Trevisan machinery, from the Trevisan DS300 to the Trevisan DS1200.
