Valve Leak Test Standards

This International Standard specifies methods for the leak testing of vacuum valves used for control of gas flow or vacuum pressure in a vacuum system. It is applicable to vacuum valves that can be closed to leak rates less than 1 × 10−5 Pa m3/s for trace gas. The...

Introduction & Scope The Metal Powder Industries Federation (MPIF) is a voluntary-membership, not-for-profit trade association formed by the members of the PM and particulate materials industry to promote the advancement of the metal powder producing and consuming industries and the practice of...

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...

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 test method is useful for quality control testing and field inspection of piping systems, pipelines, valves, and containers that are expected to retain liquids. It is not sensitive enough for leak testing when toxic or explosive gas is expected to be retained...

6.1 This practice is useful for quality control testing and field inspection of piping systems, pipelines, valves, and containers that are expected to retain liquids. It is not sensitive enough for leak testing when toxic or explosive gas is expected to be retained under...

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 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).

6.1 This practice is useful for quality control testing and field inspection of piping systems, pipelines, valves, and containers that are expected to retain liquids. It is not sensitive enough for leak testing when toxic or explosive gas is expected to be retained under...

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...

6.1 This practice is useful for quality control testing and field inspection of piping systems, pipelines, valves, and containers that are expected to retain liquids. It is not sensitive enough for leak testing when toxic or explosive gas is expected to be retained under...

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 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 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...
