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.

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.

In the wake of the COVID-19 pandemic, valve manufacturers and distributors were forced to pivot their focus and priorities to ensure the continued wellbeing of both the business and its employees. Emerson – a global software, technology and engineering leader offering the world’s largest portfolio of final control equipment and services – continued to drive innovation in the process industry through these unprecedented times, aiming to make the world healthier, safer, and more sustainable.

The newest innovation from Crane ChemPharma and Energy stacks a host of critical safety features alongside advanced performance improvements for the highest reliability in demanding service applications in chemical and refining markets.

Concerns over greenhouse gases and their impact on climate change have prompted the world to move away from fossil fuels. However, decarbonizing the industry is not an easy task, given the technological and social challenges that need to be overcome.

Badak LNG is one of the largest natural gas liquefaction plants in the world, located in Bontang, Indonesia. There are 8 process trains - capable of producing 22.5 Million Metric Tons Per Annum of LNG - and they use steam turbines for driving power generation and refrigeration compressors. On January 27, 2011, a routine inspection detected several cracks on a 24” #600 gate valve located on a steam line.

As many companies and producers of energy are looking toward establishing a cleaner future, a great amount of consideration is being put into the environmental impact of various fuels. While oil and gas will continue to be used in many industries for the foreseeable future, Hydrogen has earned a reputation as the next new form of reliable energy.
