The challenge with fail-safe processes within air reservoirs can be boiled down to the lack of standardization that results in complicated and costly assemblies.

What do successful organizations, large and small, have in common? When they are confronted with required changes to their operating systems, based on new governmental regulations, they have little recourse other than to find a solution.

Cowan Dynamics, a leading industrial valve actuator manufacturer, continues to advance valve automation with the release of the E2H-ESD.

The Nuclear Power industry is extending the operating lifespan of its reactors. Originally, reactor lifespan was planned for 40 to 60 years and is now extended to 60 to 80 years. This life extension requires regulatory approval and verification that safety-related components can meet their new service (qualified) life objectives.

This article discusses a technology approach of design & development of Knife Gate Valves consistent to the AWWA C-520 industry standard. It also describes AWWA C-520 testing requirements and an approach to qualification that goes well beyond.

It is human nature that what does not trouble one, should not worry one. But, it is critical to think about how many times during field operations we evaluate or examine functionality of valves. Precautions can be made for field maintenance of valves in special cases.

Any engineer or maintenance manager must consider a litany of valve choices for placement in their various processes. For example, critical service valves are not limited to high pressure and high temperature environments.

Water is used by homeowners, agriculture, and industry. The quantity used in residences is just a small percent of the total amount consumed. Power plants alone use ten times as much water as residential and commercial establishments.

In any modern power production facility, there are hundreds, if not thousands, of various isolation valves. In traditional thermal power production, many of these are in high pressure / high temperature service and draw the highest level of attention. These critical valves are often in thermally cyclic service and have a special set of demands associated with their applications.

Developed in 1912 by Flexitallic in response to the increasing temperature and pressure demands of the refining operations of the day, the spiral wound gasket has now been a staple in the fluid sealing industry for over 100 years.
