Patlite innovation continues with improved functionality to drive productivity, improve efficiencies, and reduce waste. One of their basic themes is to help you make continuous improvements in your process. With that in mind, Patlite introduced the LA6 multi-informational signal tower.

Trying to size and space the electrical components before the mechanics are defined can lead to wasted time and rework.

This is Part IV in a four-part series based on the contents of the new textbook, "Control Valve Application Technology, Techniques and Considerations for Properly Selecting the Right Control Valve."

Cavitation is the 2nd leading cause of a pump system failure. It's for this reason that a full understanding of what cavitation is, how it is caused, and how it can be prevented is critical in the fluid power industry.

In order to get good control with stability throughout the full range of required flow rates, one must use a control valve that has an installed flow characteristic that is linear, or at least as close to linear as possible in most systems.

Tasked with increased demand for high power output, many operators in North American sectors such as power generation, oil and gas, petrochemical, and chemical have been challenged by low-voltage solutions and their associated logistical challenges.

It's important to understand the importance of proper control valve sizing. If the valve is too small, it won't be able to pass the required flow. In actual practice, undersized valves are fairly uncommon, but oversized valves are all too common.

The Snofree Roof Panel System protects against ice formations and resulting water damage. The material, shape, and mass of its extruded aluminum core and steel enclosure maximizes the transfer of heat and minimizes energy usage.

Valin Corporation has introduced the Snofree Roof Panel System from Heat Trace Specialists, which is designed to protect facilities against ice formations and the resulting water damage. This product is part of the company's heat trace technology solutions for commercial and residential markets.

Standard practices today simply use human-machine interfaces (HMI) as windows into a system by allowing some information to be passed back and forth through those windows. This method anticipates the user having the knowledge to use that information both in and out of the system. Learn more.

Jon F. Monsen, Ph.D., P.E., a control valve technology specialist for Valin Corporation, has written a book detailing the many facets of control valves. The book, Control Valve Application Technology, Techniques and considerations for properly selecting the right control valve. Learn more.

When developing a practical approach to leakage and pollution prevention, plant managers have many options available for instrumentation and equipment. Depending on the process, materials, and operation, the method of ensuring the containment of potential contaminants will vary. Learn more.

As the automation and motion control needs of industries using control and drive functions continue to progress, the technology that meets those needs must adapt to the growing demand for connectivity, accessibility, and efficiency, all while maintaining a high level of quality and durability.

The future of the petrochemical refining industry will be driven by human-machine interfaces (HMIs) pushing information to where it is needed. An HMI that pushes production, quality and alarm information to the right level of user or management anywhere in the world has the ability to increase the visibility and reaction time.

When control valve professionals talk about "control valve sizing," they really mean the entire process of selecting the valve that will do the best job of controlling the process. Selecting the right size valve is an important part of the process, but there are other equally important considerations as well.

Purchase Valin's Control Valve Application Technology book today to learn how to apply the right techniques to selecting the correct control valves.

Advice follows on using proportional-integral-derivative (PID) tuning for motion control and robotics. High-end robotics with high dynamics and reasonably high accuracy of movement almost always require the use of these control algorithms for operation.

This is Part II in a four-part series based on the contents of the new textbook, "Control Valve Application Technology, Techniques and Considerations for Properly Selecting the Right Control Valve."

This article discusses the importance of selecting the correct flow characteristic and correctly sizing the valve in order for the valve to properly control the process.

Certain frequencies of sound can play havoc on industrial equipment. When control valves are not selected appropriately, there is an increased risk for cavitation, which causes high noise and vibration levels, resulting in very rapid damage to the valve's internals and/or the downstream piping.

Considering the number of variables, gaining precise control of a process heating application can be a difficult task. In industries with a high demand for consistent quality, controlling the temperature of a substance from the start to the finish of a process is an absolute necessity. Learn more.

IAI's new IXP Series Robots cost around 1/2 of that of a conventional model due to the adoption of the pulse motors. The IXP achieves a payload equivalent to that of a conventional model by adopting high-output drivers. All IXP models come standard with battery-less absolute encoders.

In its earliest days, Valin focused on fluid handling and developing products used in the manufacturing of semiconductor equipment and microchips. Over time, the company expanded its capabilities based on market and economic conditions.

In the chemical processing industry, a significant percentage of measurement devices are not correctly matched to their application. This leads to decreased quality and consistency in their operation.
