ABSTRACT This report presents the findings and recommendations from the third year of an American Petroleum Institute (API) research study aimed at updating the Specification 14A Verification Test Procedure for surface-controlled subsurface safety valves (SCSSV). Specification 14A was...

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...

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 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...

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 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...

1.1 These requirements cover direct-acting pressure-reducing and pressure- restricting valves intended to reduce the water pressure in standpipe systems or in the supply piping for sprinkler systems. These requirements also cover pressure- reducing valves that can...

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...

This standard covers inspection, examination, supplementary examinations, and pressure test requirements for resilient-seated, nonmetallic-seated (e.g. ceramic), and metal-to-metal-seated valves of the gate, globe, plug, ball, check, and butterfly types. Resilient seats are considered to be:...
