Valves - when to repair or replace?

When it comes to process, pilot and actuation valves, the question of whether it is advisable to repair or replace a worn or intermittent unit is worth considering, regardless of the type or the size. Tom Carnell, Systems Applications Manager, from valve manufacturer Burkert UK gives his advice as a basic guide.

Clamping systems for precision down to the smallest detail

Whether its die construction, dental technology, medical equipment or the watchmaking, jewelry or optical industries - the number of high-precision applications for micro machining has risen enormously in recent years. Anyone who wants to take an efficient approach to delicate tooling, high spindle speeds and extreme requirements for precision must have clamping systems that offer stable processes.

Reliable data connections for Industrial Ethernet

Data is everywhere and an integral part of today's control and process industries. There is nothing new about the use of data in industrial applications, but increasing volumes and real-time demands present real challenges for system designs. Planning for future system requirements is therefore an important consideration. Building extra capacity into a system for future needs starts with the architecture and is reflected in the component parts.

Looking back helps power transmission engineers to move forward

Power transmission design is a moving discipline, one which requires practitioners to consider the challenges of tomorrow when designing innovations for today. It is natural that design styles move on and that, as technologies develop and industries progress, standard approaches change and modernise. However, any good engineer will tell you that it is important to learn from the past; sometimes an older principle can be the answer to an industry's latest demands. Miroslav Slawik, Global Account Manager Basic Metal for Bauer Gear Motor, explains the evolution of gearbox design for high speed roller tables in the steel industry and how looking back may be the way forwards...

Using constant current control for metal purification

In the vast world of power supply applications, we can identify two main categories for regulating the power applied to the load. The first is "˜constant voltage', where the control loop maintains a constant voltage to varying load current demands; the second is "˜constant current' where the current is maintained constant to vary the voltage applied to the load. Giacomo Mazzullo of TDK-Lambda explains.
