Bettis EHO Electro-Hydraulic Operator (Smart)
The Bettis Smart Electro-Hydraulic Operator(EHO) is a self-contained electro-hydraulic actuator designed to actuate quarter-turn valves. It is designed to provide fail-safe actuation for Emergency Shut Down(ESD) valves. The Bettis Smart EHO has advanced diagnostic capability and can be connected to DCMlink for remote monitoring.
Features
1.Utilizes a dependable spring-return actuator for the fail-safe stroke combined with an integral hydraulic power pack and electronic control module
2.Designed as an emergency shutdown actuation solution to stop process flow upon the detection of a command signal or loss of power, protecting personnel, equipment, and the environment
3.Consistently operates in challenging environments, hostile environments, and when power is challenged
4.Over fifteen alerts and alarms to help alert users of abnormalities in the system
5.Can be integrated into systems with existing common communication protocols and DCMLink
6.Communication Protocols- HART and FOUNDATION Fieldbus, DCMlink configuration and monitoring software compatibility
7.Environmental Protection: Control enclosure: IP68, Hydraulic actuator: IP67M, Motor: IP68
