Presents fundamental theory and principles of design of pneumatic valves and controls used to regulate pressure, temperature, and flow, with no coverage of theory of control systems. Covers flow equations, the series orifice concept, characteristics of butterfly valves and actuators, and the influence of various types of control. Other subjects include flow controls, inline/poppet valves, solenoids, and torque motors, with applications from aircraft design. Includes numerous b&w simplified linearized block diagrams. No index.
