2020 VIRTUAL VALVE FORUM plus VALVE BASICS INCLUDES SEVEN LESSONS FROM OUR VALVES 101 COURSE PLUS VIDEO DEMOS! For nearly a dozen years, VMA has provided its Valve Basics course to thousands of people who are connected to or working in the valve industry and eager to enhance their knowledge: end users, specifiers, manufacturers, distributors, […]
Upgrade your valve knowledge from anywhere, with Subject Matter Expert, Davi Correia, Mechanical Engineer and Consultant. Industrial valves are complex applications and in order to ensure they perform safely and efficiently, it is crucial to not only understand how a valve works, but also all the processes associated with it, including design, manufacturing, inspection and […]
Gain insights from end-user market experts that you can use to plan, prepare and succeed. The Valve Manufacturers Association (VMA) and the Hydraulic Institute (HI) partner again in 2021 bring together global and national economic experts, as well as the experts who research and follow the economic indicators for end-use markets important to the valve […]
Valve World Americas Expo & Conference will welcome thousands of attendees to the George R. Brown Convention Center in Houston, Texas. Attendees will get a broad overview of the latest technologies, components, and systems in the field of industrial flow control presented by nearly 300 exhibitors from the United States, Asia, Canada, Europe, India, Mexico, […]
The most comprehensive virtual gathering place for all those in the valve industry value chain. The event offers solutions, content and business opportunities for the valve, valve actuator and valve automation industry. Thought leaders will present on manufacturing, technical, repair, marketing, management and other business topics. Business opportunities with networking and industry suppliers, distributors and […]
Valve closures are unavoidable, whether from emergency shutdowns, simple flow redirections, or anything in between. Figuring out the right way to close is nearly impossible without modeling software. There is no one-size-fits-all solution. The effective closure time is unique for every valve in every system - because it does not just depend on the valve […]
October 19th at 10:00 a.m. (MDT) just AFT for an in-depth look at valve behavior and how that can effect the waterhammer simulation results for the pressure response of a valve closure.
We have heard a lot about hydrogen recently, and people seem to think that it will be available in the future. In actuality it is available here and now and is in high production and high demand for industrial uses such as desulfurization units in refineries, as a fuel additive for natural gas- fired power […]
When steam turbines trip the turbine stop valve closes rapidly which generates a steam hammer transient wave. This wave can cause significant transient loads on piping. The de facto method of predicting these loads is the Goodling Method from the 1980s. AFT’s newest software product AFT xStream revealed that the Goodling Method was not always […]
Check valves are designed to protect equipment from sustained reverse flow, but a closing check valve introduces a lurking risk of secondary surge. This webinar will outline considerations for check valve selection such as the type of check valve, the system potential for reverse flow, and the deceleration of the system's fluid. AFT will take […]
When building models in AFT Arrow, you may notice the Cv/Kv loss models in valves require extra input, known as xT. This does not show up in valve models for incompressible flow, which most people are more comfortable with. ANSI/ISA-75.01.01-2012 defines xT and special considerations for compressible flow, and gives methods for control valve sizing. […]
