Electro-Hydraulic Systems These systems provide on/off or positional control of linear and rotary valves. Completely self-contained, these systems give operators the low installation costs offered by electric actuator systems, but with the power and fail-safe capabilities that have traditionally only been available from pneumatic or hydraulic systems. Paladon Americas EHYL-Series Electro-hydraulic Linear Actuators have been specifically designed to guarantee long cycle life in the most critical applications and extreme operating environments. A fabricated all-steel construction, no external threads coupled with an Ingress Protection rating of IP66 as standard.
