Valves

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. […]

Meeting Point for the Valve Community Valve World Americas Expo & Conference 2023 looks forward to welcoming 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 […]

DFT has heard a lot about carbon capture recently, which is becoming an increasingly important topic. This webinar will explore the alternative processes associated with carbon capture and the integral role of engineered check valves in these processes. During this presentation, DFT will discuss what carbon dioxide is, how it is produced, methods of capturing […]

Control valves are a common component in hydraulic systems. Whether it be controlling flow, maintaining a pressure spec, or using control valves to size equivalent equipment, it is rare to find an AFT model without control valves. This webinar will detail the various control valve options available across all AFT applications, how control valves can […]

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 to 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 and […]

Transient pressure waves exert forces on surrounding pipes in a phenomenon known as waterhammer. The damage caused by these forces can be significant, which is why the effects of waterhammer must be mitigated or avoided via operational design. This webinar will show how to define force sets while modeling a valve slam scenario, and how […]

Join DFT, Inc's webinar to gain essential insights into check valve applications in LNG services. We will explore valve selection, proper installation, and maintaining efficiency. Attendees will learn how to choose the right valves, ensure correct sizing, and comply with industry standards, helping to prevent costly issues and improve system performance. By providing practical strategies, […]
