Emerson propose un portefeuille de solutions d’automatisation des vannes de pointe pour répondre aux enjeux de sécurité et de productivité dans la régulation de débit. Des technologies d’actionnement fiables et éprouvées sur le terrain pour les actionneurs pneumatiques, hydrauliques et électriques, ainsi que des réducteurs qui conviennent à de nombreux types d’applications et de spécifications.
API 6D is a specification from the American Petroleum Institute (API) that covers valves used in oil and gas service, as well as those associated with pipelines. The API 6DX standard applies to the valve actuators and mounting kits used with these valves. The combined requirements of both standards ensure that the entire actuated valve assembly is designed to meet the stringent needs of its specific application in the energy industry, with the actuated valve package functionally tested as a complete package.
The API 6DX standard calls for a range of specific design, fabrication, inspection, testing and documentation requirements before an actuator can achieve compliance. It provides minimum sizing requirements for different types of valves, based on application (e.g., shutdown valves, blowdown valves or HIPPS valves).
In order for an actuator to be fully compliant with API 6DX, several certified test results and documents must be delivered with it. In addition, the actuator must have a securely affixed, easily accessible nameplate with permanent, legible markings, including the API 6DX mark. Several Bettis actuators are currently available in API 6DX-compliant configurations.
Bettis G-Series
Pneumatic scotch yoke actuator for 90° rotating mechanisms
Bettis CBB-Series
Compact, lightweight pneumatic scotch yoke actuator
Bettis CBA300 Series
High-performing, compact pneumatic actuator
Bettis M2CP
Rugged, easy-to-maintain electric actuator
In case of a power supply failure, a spring drives the actuator to a preset safe position. These devices are extremely reliable and require no separate maintenance.
A self-contained hydraulic emergency shutdown (ESD) system provides reliable valve shutdown capabilities in locations where power is not available or not consistent.
A piston rod and guide block connection prevents side load deflection of piston/tension rods or misalignment due to temperature or loading variations.
A turnkey valve operating package with actuator and fully integrated controls provides the ease and peace of mind of working with a single supplier.
With the spring's tension rod positively locked in place, the spring force cannot be accidentally released, enhancing personnel safety while the actuator is being serviced.
