The paper deals with steam valves as installed at large modern power stations. The types of valves dealt with are stop valves and safety valves.
In considering the former category, reference is made to design principles and applicability as well as to mechanical and metallurgical factors affecting component design. The influence of quality control techniques and commissioning hazards are discussed.
Safety valve design considerations are referred to, as are aspects of performance and noise, and also possible design trends.
