If a product is supplied bearing the API Monogram and manufactured at a facility licensed by API, the requirements of Annex A apply. This standard covers the design, material, face-to-face dimensions, pressure-temperature
This document specifies requirements for design, dimensions, material, fabrication and production testing of lined metal quarter turns valves (plug valves, butterfly valves, ball valves) and check valves with flanged, wafer and wafer lug body...
This document specifies the general requirements for metallic check valves, which are forged, cast or fabricated in straight, angle or oblique pattern (see EN 736‐2) with end connections flanged or wafer, butt welding, socket welding, or threaded. This document applies to...
This European Standard specifies the requirements for steel check valves, which are forged, cast or fabricated in straight, angle or oblique pattern (see EN 736 2) with end connections flanged or wafer, butt welding, socket welding, or threaded. This standard is applicable to...
This standard encompasses the design and performance requirements for 2, 2-1/2, 3, 3-1/2, 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, and 24 inch nominal size anti-water hammer check valves. The intended application of these devices is to permit the flow of water in one direction only,...
General Application. This Standard covers face-to-face and end-to-end dimensions of straightway valves, and center-to-face and center-to-end dimensions of angle valves. Its purpose is to ensure installation interchangeability for valves of a given material, type, size, rating...
This specification describes bronze check valves of various types for low pressure air, water, and oil services. Classification. Check valves are of the following types and classes as specified (see 6.1 and 6.2): Types. a. Type A - Swing b. Type B - Lift horizontal c....
This Standard specifies the characteristics of wafer type rubber-seated butterfly valves (hereafter referred to as "valves") to be used for piping for general equipment such as mechanical equipment, building equipment and water treatment. However, this does not apply to those...
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 versus spool...
This standard sets performance requirements for wafer carriers used in cleanrooms by evaluating the ability of these products to limit fire spread and smoke damage. All requirements in this standard shall be met in order for these products to be eligible to receive Approval recognition....
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 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).
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 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).
