36 Actuation Supplying actuators for an automated‘ Next Generation’ fully electrified offshore gas platform
Rotork has supplied over 200 actuators to ONE-Dyas for the N05-A upstream gas processing platform, located in the Dutch North Sea.
38 Severe Service Ball valve hard coating in severe service applications
Severe service generally refers to applications that feature heavy particle involvement, highfrequency cycling, extreme temperatures, corrosion, erosion, or any combination of these factors. Metalseated ball valves are required for these demanding conditions.
42 Fluid Control Torque on Valves
Valves are widely used in industrial fluid control systems to start, stop and direct flow. For the efficient and safe operation of these systems, it is of great importance to calculate the torque required when opening or closing the valves correctly. In this study, the concept of torque, the mechanisms of torque formation in valves, torque calculation methods and application examples are examined in detail.
46 Pressure Relief Valves Complying with operating pressure limits in boilers and pressure vessels
Pressure relief valves( PRVs) are designed to protect boilers, pressure vessels and piping and are considered the“ last line of defence” within industrial processes. However, an industrial process must operate in such a way that there is the highest possible productivity and in accordance with its design. In order to achieve this productivity, process operators in many companies end up working with the operating pressure very close to the valve opening pressure, causing leaks through its sealing surfaces.
50 Cryogenic Systems Safeguarding cryogenic systems with smart temperature protection
Renowned for accuracy and smart communication features, WITT’ s dome-loaded pressure regulator just got smarter: COLDSTOP SMART now detects critically low temperatures and stops gas flow to safeguard piping.
52 Cavitation Cavitation risk assessment using CFD simulations
Traditionally, cavitation assessments rely on time-consuming flow loop tests or complex multiphase CFD simulations. This article presents a more efficient alternative: using single-phase CFD simulations with pressure field correction to calculate key cavitation risk indicators like the incipient cavitation index( σ I) and liquid pressure recovery factor( FL).
56 Community Accelerating global expansion
Score, a global leader in engineering technology services in the fields of valve and emissions management, gas turbines and surface technologies, has announced its third strategic acquisition in a matter of weeks as part of its ongoing growth strategy.
60 Fugitive Emissions Valve packing sets vs packing lengths for fugitive emission applications
During the refurbishment of valves, two primary sealing solutions are typically employed. What are the advantages and disadvantages of packing sets vs packing lengths?
62 Market Outlook Looking to Southeast Asia: Innovation engine for global supply chains
In the wake of our Southeast Asia Valve World event, here is an article about the innovation and the expansion of Asian markets.
