ISA - ISA 75.02.01 - CONTROL VALVE CAPACITY TEST PROCEDURES Organization: ISA
Date: 2008-01-01
Description: 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 factors, FL and FLP c) Reynolds Number factor, FR d) Liquid critical pressure ratio factor, FF e) Piping geometry factor, FP f) Pressure drop ratio factor, xT and xTP g) Valve style modifier, Fd This standard is intended for industrial process control valves used in flow control of Newtonian fluids.
ISA - ISA 75.17 - CONTROL VALVE AERODYNAMIC NOISE PREDICTION Organization: ISA
Date: 1989-01-01
Description: The equations in this standard make use of the valve sizing factors defined in ANSI/ISA-S75.01 and ANSI/ISA-S75.02. This method was developed from the fundamental principles of acoustics, fluid mechanics, and mechanics.
ISA - ISA TR75.25.02 - CONTROL VALVE RESPONSE MEASUREMENT FROM STEP INPUTS Organization: ISA
Date: 2000-01-01
Description: It consists of a fluid containing valve body assembly, one or more ports between connection openings and a moveable closure member, which opens, restricts or closes the port(s) (see ANSI/ISA-75.05.01-2000, "Control Valve Terminology"). Actuator: An actuator is a device that supplies the force and causes the movement of the valve closure member.
ISA - ISA RP75.23 - CONSIDERATIONS FOR EVALUATING CONTROL VALVE CAVITATION Organization: ISA
Date: 1995-06-02
Description: It embodies several objectives: a) to provide educational material in a background section that condenses the literature and educates the reader in state-of-the-art valve cavitation knowledge and practice; b) to establish a basis for communication by defining cavitation parameters and nomenclature; c) to propose methods for evaluating the cavitation characteristics of individual control valves through testing procedures and application experience; and d) to offer guidelines for selecting control valves for given applications. ISA Subcommittee SP75.16 recognizes that the science of cavitation is in its infancy in terms of defining the behavior of cavitation in complex valve geometry.
ISA - ISA 75.25.01 - TEST PROCEDURE FOR CONTROL VALVE RESPONSE MEASUREMENT FROM STEP INPUTS Organization: ISA
Date: 2000-01-01
Description: Scope and limitations This standard defines the testing and reporting of step response of control valves that are used in throttling closed loop control applications. A control valve consists of the complete, ready-to-use assembly of the control valve body, actuator, and any required accessories.
DS/EN 60534-9 - INDUSTRIAL-PROCESS CONTROL VALVES -- PART 9: TEST PROCEDURE FOR RESPONSE MEASUREMENTS FROM STEP INPUTS Organization: DS
Date: 2007-11-26
Description: This part of IEC 60534 defines the testing and reporting of the step response of control valves that are used in throttling closed-loop control applications. A control valve consists of the complete, ready-to-use assembly of the control valve body, the actuator, and any required accessories.
BSI - BS EN 60534-9 - INDUSTRIAL-PROCESS CONTROL VALVES - PART 9: TEST PROCEDURE FOR RESPONSE MEASUREMENTS FROM STEP INPUTS - CORR: APRIL 30, 2009 Organization: BSI
Date: 2007-11-30
Description: Scope and object This part of IEC 60534 defines the testing and reporting of the step response of control valves that are used in throttling closed-loop control applications. A control valve consists of the complete, ready-to-use assembly of the control valve body, the actuator, and any required accessories.
ISA - ISA TR96.05.01 - PARTIAL STROKE TESTING OF AUTOMATED BLOCK VALVES Organization: ISA
Date: 2008-05-04
Description: The boundary of the automated valve includes the following: a) Limit switches and other monitoring devices b) Air regulation and filtration system c) Actuated valves whose fail position is specified as spring-return fail closed, spring-return fail open, or double acting d) Valve body specified to meet the functional requirements for its application ANSI/ISA-TR96.05.01 does not address automated valves used for regulatory control applications.
