The Concise Valve Handbook Volume II

<b>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.</b><p> 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.</p> <p>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.</p>
