Hydraulic compact actuator

Basic unit type HKA

The actuator of the type HKA is a compact electrohydraulic unit and a highduty product forming the heart of a product series following the modular construction principle. It consists of the basic unit made up of the following subassemblies: Motor, pump system, fluid tank and valve block.

Type HKAS with integrated working cylinder

In the type HKAS the basic unit is additionally equipped with an internal hydraulic working cylinder. The pressure effective inside the cylinder generates a shortstroke linear movement characte-rized by high actuating forces.

Type HKAL with external working cylinder

The actuator type HKAL is based as well on an electrohydraulic basic unit working in conjunction with an external hydraulic cylinder. The generated working pressure is transformed into a linear movement. Actuating forces and stroke length are dependent on the cylinder size. According to local requirements, the actuator may be fixed by means of flange, foot or shaft joint.
