Research studies, within the process industry routinely indicating that fluid control valves are responsible for 60 to 70% of poor-functioning control systems. Furthermore, valves in general are consistently wrongly selected, are regularly misapplied, and are often incorrectly installed. The problems lie not just within the valve itself but also with its associated ancillaries that form the final control element: the valve actuator, I/P converter and positioner. Levelled at anyone working at a technical level in the process control industry, Part 1, Sizing and construction’ provides a total in-depth insight into valve and actuator technology. Whilst 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, ancillaries – covering: control valves, check valves, shut-off valves, and solenoid valves. | The Concise Valve Handbook Volume I by Michael Anthony Crabtree, Paperback | Indigo Chapters
