ANSI Valve Standards

This standard applies to flanged globe-style control valves, sizes 1/2 inch (15 mm) through 16 inches (400 mm), having top, top and bottom, port, or cage guiding. Purpose The purpose of this standard is to aid users in their piping design by providing ANSI Class 125 flat face, and...

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...

001250-000000-000000 1 Scope 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...

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 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 analysis of...

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...

003120-000000-000000 1 Scope 1.1 These requirements cover check valves of 1 NPS and larger, used in piping systems supplying water for fire protection service. 1.2 The check valves covered by these requirements are intended for installation and use in accordance with the Standards...

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 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 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 document contains terminology for control valves. To provide a glossary of definitions commonly used in the control valve industry.

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 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...
