Uptime leap

Process safety and reliability create the foundation for sustainable efficiency and productivity in the process industry. Every process owner has strong interest in implementing all feasible measures to better manage and prevent potential risks. Advanced materials engineering solutions have great potential to contribute to the enhancement of safety and reliability in industrial processes.

Efficient valve instrumentation

Automated process valves actuated by pneumatic actuators always need pneumatic and/or electro-pneumatic instrumentation components to build up the specific functionalities required for each application. Typically, these instrumentation components are mounted all around the actuator. The number of instrumentation components available in the market is huge. Additionally, even the most common functionalities can be built in many different ways.

Rangeability - Ask the flow control expert

The term rangeability does not have a well-established definition. It is usually defined in vague terms. Basically, there are two definitions of rangeability: one for inherent rangeability, and the other for installed rangeability

Environment and economy shaking hands

LignoBoost receives Silver Award at ATIP Congress

Valmet was honored with the “Palme d’Argent” for its LignoBoost in the annual congress of ATIP in Grenoble, France.

Tackling the stock preparation and wet end challenge

Stock preparation and wet end processes are typically full of unknowns for board and paper makers. Ville Piikkilä, Business Manager for Valmet Board and Paper Automation Solutions, explains how to turn these unknowns into new benefits.

Troubleshooting headbox corrosion, plus an analysis case study

Imperfections in a headbox's finish interfere with fiber flow through its chambers, resulting in sheet uniformity problems and a poor end product. A process and condition test can identify problems caused by corrosion, fiber orientation and machine limitations.

Protect costly soft roll covers with novel mechanical devices

Soft rolls represent a significant investment for mills, yet they are susceptible to damage, especially if the surface temperature varies too much across the face of the roll. This article describes the design, operation and maintenance of some of the most common soft roll protection devices.

Proper bearing lubrication and modernization are essential

Most bearing failures can be traced to two maintenance oversights: a lack of lubrication or the use of the wrong type of lubrication. An upgrade may be needed.
