Most people who are familiar with control valves have seen the formula for calculating the valve capacity (Cv) required to pass a given flow rate of water. This seems fairly straightforward until you ask yourself, what is the correct value of differential pressure to use?
In this video, Nathan will be focusing on how to increase productivity, which is a key initiative for any company wanting to increase market share in today’s challenging economy. He will be focusing on the Watlow Aspyre power controller and its role in helping increase productivity.

Over 90% of manufacturing facilities world-wide use compressed air as part of their manufacturing process. However, this powerful utility is not without its problems, in the form of compressed air contamination. It is therefore common practice to install compressed air filters as part of a “purification system” to ensure contaminants are reduced and the system operates in a safe, efficient and cost effective manner.

There are several different processes that require a product to flow through a pipe from one piece of equipment to another. A certain level of heat is often required for this process piping, and this heat must be at very high levels for many applications.

Proper filtration is essential to process flow operation. Improper filtration or lack of filtration can wreak havoc on components, reducing their life and changing the final product. If left unaddressed, this can lead to equipment failure, process upsets, increased quality issues and in some cases, unplanned shutdown. Thus, making an investment in the correct filter for the process is a wise choice.
Varnish is a common problem for a wide range of hydraulic fluids and lubricants, especially in turbine and plastic injection molding applications. It results in valve sticking, shorter fluid life, shorter filter life and unscheduled downtime.
