Pipeline valves are designed and manufactured in compliance with API 6D and ISO 14313 standards, and are suitable for use on transmission lines adhering to ASME B31.3, ASME B31.4, ASME B31.8, or equivalent standards.
KOSEN offers a range of through-conduit isolation valves that minimize flow pressure drop, including full-opening non-return valves such as trunnion-mounted ball valves, through-conduit gate valves, and full-opening swing check valves.
KOSEN isolation valves can be configured with various isolation features, including double block and bleed, and/or double isolation and bleed configurations.
Elastomeric and thermoplastic (soft) seating are typically used for clean services or dormant, buried valves, while metal-to-metal seated configurations are available for critical isolation applications such as scraper launching and receiving facilities, crude oil, and erosive/dirty services.
KOSEN valves can be actuated with pneumatic, direct gas, gas-over-oil, or electro-hydraulic units, with line break functionality available upon request.
