Book Description
This SAE Standard applies to hydraulic directional control valves as applied to self-propelled work machines referenced in SAE J1116. It describes a laboratory test procedure for evaluating: aFlow versus pressure drop bLeakage rate cOperating effort dMetering characteristics versus spool travel, pilot pressure, or electrical current eRelief valve characteristicsThe document applies to single and multiple section hydraulic directional control valves.This document illustrates axial, manually operated valves although the test procedure is applicable to other input forms such as rotary actuation, electric current, hydraulic or pneumatic pressure.Performance characteristics such as metering hysteresis or dynamic response may have a significant effect on some of these tests. Major revision to update reference standards, change verbiage in regards to pressure and flow rating, valve test criteria, and figures containing worksheets and data plots.

Book Description
The latest update to Bela Liptak's acclaimed "bible" of instrument engineering is now available. Retaining the format that made the previous editions bestsellers in their own right, the fourth edition of Process Control and Optimization continues the tradition of providing quick and easy access to highly practical information. The authors are practicing engineers, not theoretical people from academia, and their from-the-trenches advice has been repeatedly tested in real-life applications. Expanded coverage includes descriptions of overseas manufacturer's products and concepts, model-based optimization in control theory, new major inventions and innovations in control valves, and a full chapter devoted to safety. With more than 2000 graphs, figures, and tables, this all-inclusive encyclopedic volume replaces an entire library with one authoritative reference. The fourth edition brings the content of the previous editions completely up to date, incorporates the developments of the last decade, and broadens the horizons of the work from an American to a global perspective. Béla G. Lipták speaks on Post-Oil Energy Technology on the AT&T Tech Channel.

Book Description
Provides a test procedure for obtaining the following factors for sizing control valves: valve flow coefficient (Cv); liquid pressure recovery factors (Fl and Flp); Reynolds Number factor (Fr); liquid critical pressure ratio factor (Ff); piping geometry factor (Fp); & pressure drop ratio factors (Xt & Xtp). The standard is intended for control valves used in flow control of process fluids & is not intended to apply to fluid power components as defined in the National Fluid Power Association Standard NFPA T.3.5.28-1977.
