Available in PDF, EPUB and Kindle. Book excerpt: Control valves are imperative elements in any system where fluid flow must be monitored and manipulated. A complete control valve is made of the valve itself, an actuator, and, if necessary, a valve control device. The actuator is what provides the required force to cause the closing part of the valve to move and the valve control devices keep the valves in the proper operating conditions; they can ensure appropriate position, interpret signals, and manipulate responses.Selection of the proper valve involves a thorough knowledge of the process for which it will be used. When implementing a control valve into a process, one must consider not only the appropriate type of valve and its material of construction, but also the correct sizing to ensure it performs its designated task without any adverse occurrences in the system.This 4-hour quick book provides an overview of control valve with emphasis on the sizing and selection. This course is for mechanical, instrumentation and process engineers involved in sizing, selecting and applying process control valves. No specific prerequisite training or experience is required.Learning ObjectiveAt the conclusion of this course, the reader will:• Differentiate between various types of valves and the benefits of each;• Understand the operation of control valve in a control loop;• Understand how to evaluate and apply actuators and positioners for specific applications;• Understand the basic hydraulics and the relationship between the Cv, flow rate and pressure drop;• Understand how to size valves for any flow condition likely to be found in a process plant;• Understand how to select the proper valve characteristic for a given process;• Understand how the installed characteristics can match closely to the inherent characteristics;• Understand the methods to address system performance issues such as cavitation, flashing and chocked conditions;• Understand the factors influencing the selection of control valves.

Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. Over recent years, a number of significant developments in the application of valves have taken place: the increasing use of actuator devices, the introduction of more valve designs capable of reliable operation in difficult fluid handling situations; low noise technology and most importantly, the increasing attention being paid to product safety and reliability. Digital technology is making an impact on this market with manufacturers developing intelligent (smart) control valves incorporating control functions and interfaces. New metallic materials and coatings available make it possible to improve application ranges and reliability. New and improved polymers, plastic composite materials and ceramics are all playing their part. Fibre-reinforced plastic pipe systems, glass-reinforced epoxy pipe systems and the traditional low-cost polyester pipe systems have all undergone sophisticated design and manufacturing technology changes.

Available in PDF, EPUB and Kindle. Book excerpt: In the fields of work in industrial areas, engineers and project implementers work to find means to develop the work and complete it at time indicated in an implementation plan and to avoid delay in the progress of the project for many reasons that we cannot summarize here for its bifurcation and relationship of activities with each other, but we mention the most important reason at which the failure to follow the standard specifications of activities construction of the project by engineers or technicians. These standards and codes are usually mentioned their sources in the project documents. The deviation from following the standards and codes leads to technical errors and consequently to the re-work and an addition of unwanted time to the project activity, and when errors are repeated due to non-compliance with international standards, this will result in an accumulation of the unwanted time in the project, ultimately leads to deviating the project plan.

Book excerpt: This SAE Standard applies to hydraulic directional control valves as applied to self-propelled work machines referenced in SAE J1116. It describes a laboratory test procedure for evaluating: aFlow versus pressure drop bLeakage rate cOperating effort dMetering characteristics versus spool travel, pilot pressure, or electrical current eRelief valve characteristicsThe document applies to single and multiple section hydraulic directional control valves.This document illustrates axial, manually operated valves although the test procedure is applicable to other input forms such as rotary actuation, electric current, hydraulic or pneumatic pressure.NOTEPerformance characteristics such as metering hysteresis or dynamic response may have a significant effect on some of these tests. In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an enclosed circuit. The hydraulic fluid power control valve is used to direct and control the fluid in the circuit to achieve the desired functions and flow of the fluid.The pressure drop, leakage rate, operating effort, metering characteristics and relief valve characteristics are indications of the ability of the control valve to perform the desired functions.The test procedure has been a recommended practice since 1956, last revised in 1975 and a five year review was started in 1982. Since several documents have been written which describe certain tests in more detail, they have been incorporated into this procedure. Also, the wording has been revised to expand the scope of the procedure to include other input forms in addition to direct manual operation.After a number of rewrites and input from manufacturers and end users, the revised test procedure was balloted in ORMTC SC4 on July 16, 1987, with fifteen approvals, one disapproval, and seven no replies. The subcommittee also recommended to upgrade the document to a standard and to submit the document to ANSI. The document has been revised to resolve the disapproval and include revisions from comments on the approval ballots.

Available in PDF, EPUB and Kindle. Book excerpt: This book addresses a seemingly simple question: Can a certain amount of gas be transported through a pipeline network? The question is difficult, however, when asked in relation to a meshed nationwide gas transportation network and when taking into account the technical details and discrete decisions, as well as regulations, contracts, and varying demands, involved. This book provides an introduction to the field of gas transportation planning and discusses in detail the advantages and disadvantages of several mathematical models that address gas transport within the context of its technical and regulatory framework, shows how to solve the models using sophisticated mathematical optimization algorithms, and includes examples of large-scale applications of mathematical optimization to this real-world industrial problem. Readers will also find a glossary of gas transport terms, tables listing the physical and technical quantities and constants used throughout the book, and a reference list of regulation and gas business literature.

Available in PDF, EPUB and Kindle. Book excerpt: This two-volume book comprises a comprehensive up-to-date body of knowledge that provides a total in-depth insight into valve and actuator technology – looking not just at control valves, but a whole host of other types including: check valves, shut-off valves, solenoid valves, and pressure relief valves. Research studies within the process industry routinely indicate that the fluid control valve is responsible for 60 to 70% of poor-functioning control systems. Furthermore, valves in general are consistently wrongly selected, regularly misapplied, and often incorrectly installed. A methodology is presented to ensure the optimum selection of size, choice of body and trim materials, components, and ancillaries. Whilst studying the correct procedures for sizing, readers will also learn the correct procedures for calculating the spring ‘wind-up’ or ‘bench set’. Maintenance issues also include: testing for deadband/hysteresis, stick-slip and non-linearity; on-line diagnostics; and signature analysis. Written in a detailed but understandable language, the two volumes are presented in a form suitable for both the beginner, with no prior knowledge of the subject, and the more advanced specialist.
