Bettis EHO electrohydraulic actuator for critical shutdown applications

Click2Contact

Emerson Process Management has expanded its process valve automation range with the release of the Bettis EHO actuator. The EHO is a robust electrohydraulic actuator that couples proven technologies from the company’s valve actuation range to handle critical shutdown situations where dependability is a must.

The actuator is suitable for a diverse range of applications, from topsides valve automation on offshore platforms to remote pipelines where operational upsets can cause safety and environmental hazards, as well as costly production losses. To help operators counteract these challenges, the EHO provides a compact design with actuator and control components from Emerson that have been field proven in critical service.

The actuator is available in either spring-return or double-acting configurations. Torque outputs can handle valve sizes from 6 to 60″. The actuator operates on utility electrical power or optional solar power for remote areas where electric power is not available or not reliable. The EHO is operable in temperatures ranging from -40 to +60°C, and its fail-safe capability is reliable with fast close or open stroke times, suitable for emergency shutdown in oil or gas service.
