Bettis EHO Electro-Hydraulic Operator (Standard)

The Bettis Standard Electro-Hydraulic Operator (EHO) is a self-contained electro-hydraulic actuator designed specifically for actuating quarter-turn valves. Its primary function is to provide fail-safe actuation for Emergency Shutdown (ESD) valves, ensuring rapid and reliable valve operation in emergency situations. The system offers a straightforward, reliable solution for ESD applications, functioning effectively in hostile environments and situations where power may be unavailable.

Key Features

• Spring-Return Actuator: Features a spring-return actuator for fail-safe stroke, ensuring the valve returns to the safe position in case of power loss.

• Emergency Shutdown (ESD) Solution: Stops process flow upon receiving a command signal or power loss, protecting personnel, equipment, and the environment.

• Resilient in Challenging Environments: Performs reliably in hostile environments and when power is disrupted.

• Alerts and Alarms: Over 15 alerts and alarms to notify users of system abnormalities.

• Integration Compatibility: Compatible with common communication protocols (HART, FOUNDATION Fieldbus) and DCMlink configuration and monitoring software.

• Environmental Protection:

  • Control enclosure: IP68

  • Hydraulic actuator: IP67M

  • Motor: IP68
