| Sumario: | Research studies, within the process industry, routinely indicate that the final control element is responsible for 60% to 70% of poor-functioning control systems. Although valves themselves are consistently wrongly selected, regularly misapplied, and are often incorrectly installed, a large proportion of the blame may also be attributed to a number of associated ancillaries: the valve actuator, I/P converter, and positioner. Levelled at anyone working at a technical level in the process control industry, Volume I: Sizing and construction provides a total in-depth insight into valve technology. While studying both liquid and gas valve sizing, the guide also presents a methodology to ensure the optimum selection of type, size, body and trim materials, components, and ancillaries--covering: control valves, check valves, shut-off valves, and solenoid valves. Volume II: Actuation, Maintenance, and Safety Relief, takes an in-depth look at actuators and positioners. This volume also explores a variety of maintenance and diagnostic issues including: testing for dead-band/hysteresis, stick-slip and non-linearity; on-line diagnostics; signature analysis; and correct procedures for calculating the spring "wind-up" or "bench set." A complete section is also devoted to the whole field of safety relief devices. Lastly, this volume covers a number of topics which are all too often ignored: acoustics; water hammer; and even classification of stainless steel. |
