This document contains terminology for control valves. To provide a glossary of definitions commonly used in the control valve industry.
This document discusses control valve stem position mechanical stability and establishes a measurement criterion for position instability of the valve. Other forms of instability associated with control valves and control systems are not covered. Purpose...
SCOPE & LIMITATIONS Selection of a leakage class is not restricted as to valve design, but acceptable values for various commercially available designs are suggested for each class under Section 4. This standard applies to control valve seat leak production testing and cannot...
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: a Flow versus pressure drop b Leakage rate c Operating effort d Metering characteristics...
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: a.) Flow versus pressure drop, b.) Leakage rate, c.) Operating effort, d.) Metering...
This test standard utilizes the mathematical equations outlined in ANSI/ISA-75.01.01 (IEC 60534-2-1 Mod)-2007, Flow Equations for Sizing Control Valves, in providing a test procedure for obtaining the following: a) Valve flow coefficient, C (Cv, Kv) b) Liquid pressure recovery...
This standard establishes a method to predict the noise generated in a control valve of standard design by the flow of compressible fluid and the resulting noise outside of the pipe and downstream of the valve. The transmission loss (TL) equations are based on a rigorous...
This technical report applies to throttling control valves in closed loop control applications. The concept has some application to open loop control applications. It does not address control valves used in on-off control service. The "control...
IEC 60534-7:2010 provides a list of requirements that are necessary for the procurement of the majority of control valves for process systems. The list is arranged to assist the specification writer with a standardized presentation of data and also to be a basis for use with data...
Includes insights on valve sizing, smart (digital) valve positioners, field-based architecture, network system technology, and control loop performance evaluation. Hans Baumann, a holder of more than 150 patents, and author of over a hundred publications in control...
This part of the IEC 60534 series provides a list of requirements that are normally necessary for the procurement of the majority of control valves for process systems. No attempt is made to include all possible requirements for any conceivable process. The list is arranged in a...

This recommended practice is intended for control valves used in the control of process fluids and is not intended to apply to fluid power components. The reader and user should be familiar with fluid mechanics fundamentals and ISA standards ANSI/ISA S75.01 and ANSI/ISA S75.02...
Production acceptance and type (or qualification) tests. Applicable to 2-, 3- and 4-way flow control valves and to 2-way pressure control valves.
The purpose of this SAE Information Report is to define common industry terminology and nomenclature relative to thermal flow control valves and to describe common thermal flow control valve applications in automotive, highway truck, mobile construction equipment, and...
This Standard specifies the terminology of all types of industrial-process control valves (hereafter referred to as control valves) and general considerations. NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are...
