M49 Quarter-Turn Valves: Head Loss, Torque, and Cavitation Analysis, Third Edition

By Awwa

This manual presents a recommended method for calculating operating torque, head loss, and cavitation for quarter-turn valves typically used in water works service. M49 also provides guidance on generally available methods for using quarter-turn valves as well as their cavitation, flow, and torque characteristics. _x000d_
This manual was previouslytitled M49 Butterfly Valves, but this third edition has broadened the application of the methods discussed to include other quarter-turn valves such as ball, plug and rotary cone valves. Additionally, new information on Equivalent Resistant System Model has also been included. _x000d_
Information in this manual is useful for technicians and engineers who want a basic understanding of the calculations associated with the use and specification of quarter-turn valves. _x000d_
