| valve selection and specification guide: Valve Selection and Specification Guide Ronald C. Merrick, 1991-01-10 Today, people who specify or select valves spend over two-thirds of their time researching literature for information on valve sizing, availability, materials, and standards. This is nonproductive time. Unfortunately, most companies do not have the luxury of a team of experts with the necessary experience and education in all of the different fields that apply to valves. The next best alternative is to understand what valves are and all the things they can do. By definition, valves are devices that stop, start, mix, or change the direction and/or magnitude of the fluid flow, pressure, or its tempera ture. As a specifier or selector you will have to determine whether the valve is going to be used for flow control, throttling, or for on-off service. Then you will have to determine the cycle life or frequency of their operation. You will discover that valves are classified into three categories: on-off valves, control or regulator valves, and fixed valves such as orifice plate, nozzle, duckbill, rupture disk, blind valve, etc. These valves represent approximately thirty different design configurations. It has been said that if cost and delivery were no problem, anyone of the seven basic valve styles could do the job of any other one. But cost and delivery are very important factors in the real world. So you have to be able to distinguish among these seven styles: ball, butterfly, gate, globe, pinch/ diaphragm, plug, and poppet valves. |

| valve selection and specification guide: Subsea Valves and Actuators for the Oil and Gas Industry Karan Sotoodeh, 2021-05-29 Piping and valve engineers rely on common industrial standards for selecting and maintaining valves, but these standards are not specific to the subsea oil and gas industry. Subsea Valves and Actuators for the Oil and Gas Industry delivers a needed reference to go beyond the standard to specify how to select, test, and maintain the right subsea oil and gas valve for the project. Each chapter focuses on a specific type of valve with a built-in structured table on valve selection, helping guide the engineer to the most efficient valve. Covering subsea-specific protection, the reference also gives information on high pressure protection systems (HIPPS) and discusses corrosion management within the subsea sector, such as Hydrogen Induced Stress Cracking Corrosion (HISC). Additional benefits include understanding the concept of different safety valves in subsea, selecting different valves and actuators located on subsea structures such as Christmas trees, manifolds, and HIPPS modules, with a full detail review including sensors, logic solver, and solenoid which is designed to save cost and improve the reliability in the subsea system. Rounding out with chapters on factory acceptance testing (FAT) and High Integrity Pressure Protection Systems (HIPPS), Subsea Valves and Actuators for the Oil and Gas Industry gives subsea engineers and managers a much-needed tool to better understand today's subsea technology. - Understand practical information about all types of subsea valves and actuators with over 600 visuals and several case studies - Learn and review the applicable standards and specifications from API and ISO in one convenient location - Protect your assets with a high-pressure protection system (HIPPS) and subsea-specific corrosion management including Hydrogen Induced Stress Cracking Corrosion (HISC) |

| valve selection and specification guide: StarBriefs 2001 , 2012-12-06 This compilation probably looks like one of the craziest things a human being could spend his or her time on. Yet nobody would wonder at someone taking a short walk every day - after twenty five years that person would have covered a surprisingly long distance. This is exactly the story behind this list, which appeared first as a few pages within the directory StarGuides (or whatever name it had at that time) and as a distinct sister publication since 1990. The idea behind this dictionary is to offer astronomers and related space scientists practical assistance in decoding the numerous abbreviations, acronyms, contractions and symbols which they might encounter in all aspects of the vast range of their professional activities, including traveling. Perhaps it is a bit paradoxical, but if scientists quickly grasp the meaning of an acronym solely in their own specific discipline, they will probably encounter more difficulties when dealing with adjacent fields. It is for this purpose that this dictionary might be most often used. Scientists might also refer to this compilation in order to avoid identifying a project by an acronym which already has too many meanings or confused definitions. |
