tailieunhanh - Valve Selection Handbook - Fourth Edition

Valves are the controlling elements in fluid flow and pressure systems. Like many other engineering components, they have developed over some three centuries from primitive arrangements into a wide range of engineered units satisfying a great variety of industrial needs. The wide range of valve types available is gratifying to the user because the probability is high that a valve exists that matches the application. But because of the apparently innumerable alternatives, the user must have the knowledge and skill to analyze each application and determine the factors on which the valve can be selected. He or she must also have sufficient knowledge of valve types and their construction. | VALVE SELECTION HANDBOOK Engineering fundamentals for selecting manual valves check valves pressure relief valves and rupture discs FOURTH EDITION VALVE SELECTION HANDBOOK FOURTH ED This page intentionally left .
