Electro-Hydraulic Actuators and Specialty Cylinders

Electro-hydraulic Actuators

Special projects that demand the plumbing-free convenience of electric actuators and the large forces of hydraulic cylinders are provided by Passion’s custom electro-hydraulic actuators. Passion’s EHAs provide both motion control precision and protection against shocks and over-loads. Our custom engineered and packaged hydraulic power unit, cylinder, transducer, and controller units are ideal for industrial, marine, and infrastructure projects requiring precision, high-force actuators that are easy to install and maintain.
