Servohydraulic Testing Actuators

Servo-hydraulic testing actuators are used in materials and component testing to reproduce precise, pre-determined forces and travel. They can be integrated into a load frame (Models HA, HB, HC) or mounted on a platform as a single testing actuator.

Hydraulic Power Packs

Servo-hydraulic test equipment requires a pressurized oil supply with an extremely high level of cleanliness and constant pressure. Pressure fluctuations must be minimal at all times, even with very irregular oil demand from the consumer.

Specimen Grips

Zwick hydraulic wedge grips are suitable for static tensile and compression tests, as well as for fatigue tests under pulsating and alternating loading.

Controller HydroWin 96xx

HydroWin 96xx ControllerHydroWin 96xx measurement and control electronics can be used for static, quasi-static and dynamic tests on materials, components and complete structures.

Hydraulic Connector Unit

The hydraulic connector unit is the electrically operated control center for servo-hydraulic testing systems. It switches the hydraulic pressure supply to a servo-hydraulic single testing actuator or servo-hydraulic testing machine on or off.

Servo Valves

Servo valves are used in closed control loops for high-accuracy control of hydraulic energy, with multi-kilowatt hydraulic power controlled by milliwatt-range input signals.

Hydraulic Pipelines

Hydraulic pipelines are used when the distance between pressure generator and consumer is too great for hoses. As a general guide, a pipeline should be used for runs of 10 - 12 meters and above. In contrast to hoses they do not have to be replaced at regular intervals.
