The Complete Valve Primer – a definitive guide

Research studies within the process industry routinely indicate that the fluid control valve is responsible for 60 to 70% of poor-functioning control systems. This book ‘The Complete Valve Primer – a definitive guide’ is a complete in-depth manual covering all aspects of valve technology and includes more than 140 explanatory drawings – clearly showing the construction of a wide range of valves that includes: control valves; shut-off valves; check valves; and pressure relief and safety valves. A large section is also devoted to covering the fundamental principles of converters, actuators, and positioners. Readers are presented with an insight into flashing, cavitation, noise generation, leakage problems, a complete overview of valve sizing, and the correct procedure for calculating the spring ‘wind-up’. Routine maintenance and repair issues are also covered, as well as diagnostic methodologies for testing for deadband/hysteresis, stick-slip and non-linearity;and signature analysis.
