Electro-hydraulic actuators (EHAs) use electrical power to operate valves via pressurized hydraulic fluid. They feature a built-in hydraulic pump, eliminating the need for separate pumps and tubing, which simplifies system design and enhances safety. EHAs are now used in various industries for both linear and rotary valves, providing high torque, thrust, and fail-safe capabilities while streamlining system construction and improving reliability.
