This standard includes equations for predicting the flow of compressible and incompressible fluids through control valves. The equations for incompressible flow are based on standard hydrodynamic equations for Newtonian incompressible fluids. They are not intended for...
This Standard provides the requirements and test methods for the safety performance of high pressure gas valves that are used in gaseous hydrogen stations of up to the H70 designation. This standard covers the following gas valves: - check valve - excess flow...
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 standard sets performance requirements for liquid and gas safety shutoff valves, fire safe (class 7440) and non-fire safe (Class 7400), used in the supply lines of commercial and industrial burners as well as in ignitable liquid piping systems. Safety shutoff valves are intended...
This SAE Aerospace Standard (AS) defines minimum standards of design, construction, and performance for two types of permanently installed, high pressure 12,800 kPa (1850 psig) and 13,800 kPa (2000 psig) oxygen system cylinder fill valves used in commercial aircraft. Refer to Purchaser's...
This International Standard provides the minimum acceptable requirements for subsurface safety valves (SSSVs). It covers subsurface safety valves including all components that establish tolerances and/or clearances which may affect performance or interchangeability of the SSSVs. It...
This part of IEC 60534 establishes a method to predict the noise generated in a control valve by liquid flow and the resulting noise level measured downstream of the valve and outside of the pipe. The noise may be generated both by normal turbulence and by liquid...
This part of IEC 60534 establishes a method to predict the noise generated in a control valve by liquid flow and the resulting noise level measured downstream of the valve and outside of the pipe. The noise may be generated both by normal turbulence and by liquid...
This part of ISO 10094 specifies which characteristics of electro-pneumatic continuous pressure control valves are to be included in the supplier's literature. In accordance with ISO 5598, these control valves include - electrically modulated pneumatic proportional...
Describes procedures for the determination of sound power levels of a hydraulic fluid power valve under controlled conditions of installation and operation, suitable for providing a basis for comparing the noise levels of valves.
This Aerospace Recommended Practice (ARP) provides recommendations for the design and test requirements for hydraulic flow regulators (also known as flow control valves). The hydraulic flow regulator is intended for use in a civil or a military aircraft hydraulic...
IEC 60534-8-4:2015 establishes a method to predict the noise generated in a control valve by liquid flow and the resulting noise level measured downstream of the valve and outside of the pipe. The noise may be generated both by normal turbulence and by liquid cavitation...
1.1 This standard includes mounting surfaces for the following: - non-return (check) valves; - compensated flow control valves; - directional control valves; - pilot operated non-return (check) valves; - pressure control valves; -...
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 section of Part 2 covers equations suitable for use in sizing industrial-process control valves when the flowing media are compressible fluids. At very low ratios of pressure differential to absolute inlet pressure (∆plp1), compressible fluids behave similarly to incompressible...
ABSTRACT This report presents the findings and recommendations from the second year of an American Petroleum Institute (API) research study aimed at updating the API Specification 14A Verification Test Procedure for surface-controlled subsurface safety valves (SCSSV). Specification...
This International Standard provides the requirements for subsurface barrier valves and related equipment as they are defined herein for use in the petroleum and natural gas industries. Included are the requirements for design, design validation, manufacturing, functional evaluation, repair,...
ESDU 69022 gives approximate pressure loss information for single-phase flow through a number of types of shut-off and simple flow control valves. The information is presented in the form of non-dimensional pressure loss coefficients and applies for the flow of...
