How to select check valves on dynamic performance rather than line size: slam and surge, non-slam curves, flutter from oversizing, installation rules and why a check valve is not an…
How control valve noise is generated and predicted under IEC 60534-8-3, how low-noise trim works, and why acoustically induced vibration is the real hazard.
How cryogenic valves are designed and qualified: extended bonnet thermal design, material selection, cavity relief, BS 6364 testing and what changes for liquid hydrogen.
Shell tests, seat tests and leakage classes explained: API 598, ISO 5208, EN 12266, FCI 70-2, NDE methods and how to specify valve testing without ambiguity.
How to size valve actuators properly: break-to-open and seating torque, dynamic torque, safety factors, spring-return constraints, MAST limits and stroking speed.
How to size a control valve properly: flow coefficients, choked flow, valve authority, installed characteristic, rangeability and the real cost of oversizing.
A working guide to valve material selection: carbon steel limits, austenitic and duplex stainless, nickel alloys, trim hardfacing, NACE sour service and bolting.
What fire testing actually proves, how API 607, API 6FA and ISO 10497 differ, and the design features that let a valve isolate during and after a hydrocarbon fire.
A practical guide to valve stem fugitive emissions: how ISO 15848 and the API 622/624/641 family differ, what packing and live loading really do, and how to specify low emission…
How cavitation and flashing damage control valves, how to predict them with sigma and FL, and the trim, material and piping decisions that actually solve the problem.
