1.1 These minimum requirements cover the following types of anhydrous ammonia and liquefied petroleum gas (LP-Gas) valves that are used to control the flow of liquid and/or vapor into and out of containers, or in piping systems between containers, or between containers and utilization...
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...
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 valve" in the context of this...
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...
This specification is applicable to all valve springs, ready for installation, which are manufactured from alloy spring steel. Mission / Theme. Not applicable. Classification. Not applicable. Note: Nothing in the specification, however, supersedes applicable laws and regulations unless a...
This Recommended Practice (RP) provides general guidance on valve selection for the hydrocarbon processing industry (HPI), which includes refineries and petrochemical, chemical, and liquefied natural gas (LNG) plants and their various associated processes. Selection guidance is provided for...
This specification covers an outlet valve which has a plastic valve seat, cover and a rubber disk. The valve is a component of a chemical protective mask (see 6.1).
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 be used...
This SAE Information Report provides: a Types of valve guides and their nomenclature b Valve guide alloy designations and their chemistries c Valve guide alloy metallurgy d Typical mechanical and physical properties of guide alloys e Typical dimensional tolerances of...
This document contains terminology for control valves. To provide a glossary of definitions commonly used in the control valve industry.
This standard specifies the requirements for the general design and manufacturing requirements for valves and actuators for fluid systems in surface ships and submarines. This standard covers valves for both High Pressure (HP) and Low Pressure (LP) fluid systems, however specific...
This book provides information on the aortic valve. Written in a comprehensive style, it emphasizes the principles behind the development of artificial valves. It covers the principles of valve geometry, tissue structure and function relationships, valve dynamics, fluid...
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 This document is...
Revised to include details on the latest technologies, Valve Handbook, Third Edition, discusses design, performance, selection, operation, and application. This updated resource features a new chapter on the green technology currently employed by the valve industry, as well as an...
This specification establishes the requirements for the manufacture and acceptance of the 3-way solenoid valve (also known as the Mode Selector Valve (MSV)), used in the Fire Control System for the M109A6 Self-Propelled Howitzer (SPH) (see 6.1).
This recommended practice (RP) provides recommendations for evaluation of a manufacturer's valve construction and quality management system for the purpose of determining a manufacturer's capability to provide new valves manufactured in accordance with the applicable standards listed...
This Practice provides the detailed purchase descriptions for carbon steel gate valve tag numbers included in PIP Piping Material Specifications and used along with PIP PNSM0110 for the procurement of valves. This Practice also provides a cross reference for carbon steel gate...
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...
Preface Over the past few years transesophageal echocardiography has become one of the most exciting imaging modalities available today in modern clinical cardiology. Transesophageal echocardiography and MRI imaging has substantially improved our understanding of mitral valve anatomy and...
