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...

This European Standard applies primarily to copper alloy ball valves, dimensions DN 8 to DN 100, for potable water supply in buildings up to PN 10 and a distribution temperature of 65 C. Occasional excursions up to 90 C are permitted for a period of 1 h maximum. This standard applies...

This document specifies requirements for design, manufacture and test methods of cryogenic ball valves in order to have an excellent quality leakage stability in a very low temperature service (−196 °C to 80 °C).

This document specifies requirements of design, manufacture, and test methods for cryogenic ball valves in order to have excellent quality of leakage stability in a very low temperature service(−196°C~+100°C) .

This standard describes plastic ball valves for water supply service. This standard covers threaded, union, fusion, or compression ended double- and single-seated nonmetallic ball valves for pressures 100 psi (689 kPa) and higher in sizes from ½-in. through 2-in. (13-mm...

This Standard Practice establishes requirements for plastic industrial ball valves in nominal pipe sizes (NPS) 1/2 through NPS 6, designed for general industrial systems for the distribution of pressurized liquids that are chemically compatible with the piping material. It reflects...

Valve seat and body pressure/temperature ratings, the design, materials, dimensions, operation, performance, testing and marking of straightway steel ball valves having specified wall thickness, antistatic feature and fire tested design. Valves of PN 10 to...

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 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 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.
