Check Valve Design Standards

The CRSI Design Handbook has been the reference book for cast-in-place reinforced concrete design since 1952. The 10th edition provides the necessary information needed for common reinforced concrete structural members such as columns, beams, footings, pile caps, retaining walls, and...

This SAE Aerospace Recommended Practice (ARP) provides recommendations for the design and test requirements for a spring-loaded, normally-closed hydraulic check valve. The check valve is intended for use in a civil or military aircraft hydraulic system with a...

This document specifies requirements of design, manufacture, and test methods for cryogenic check valves to have excellent quality of leakage stability in very low temperature environments (−50 °C to −196 °C)

This document specifies requirements of design, manufacture, and test methods for cryogenic check valves to have excellent quality of leakage stability in very low temperature environments (−50 °C to −196 °C).

This International Standard specifies requirements of design, manufacture, test methods for cryogenic check valves in order to have excellent quality leakage stability in very low temperature environments (-50°C ~ -196°C).

This standard describes the double check-valve backflow prevention assembly for potable water applications. The assembly shall be capable of withstanding a working water pressure of at least 150 psi (1,034 kPa) without damage to working parts or impairment of function and for...

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...

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...

Description These devices consist of two (2) independently acting check valves internally force loaded to a normally closed position and designed to operate under intermittent or continuous pressure conditions. These devices shall be permitted to be equipped with a...

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,...

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 part of ISO 13693 specifies the construction and performance requirement and test methods for metal-bodied chemigation valves with water at temperatures not exceeding 50 °C, which might contain fertilizers and chemicals of the types and concentration used in agriculture. The...

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...
