The hydraulic damper is an additional module used to lengthen actuation time and achieve an evenly constant actuation speed.

It utilises a piston that oscillates inside a cylinder containing a hydraulic medium; because the fluid is incompressible, it resists jerky movements.

No, the torque remains the same even when the damping module is engaged.

It is primarily deployed for "slamming" valves, such as double-eccentric butterfly valves, where controlled movement is critical.

Yes, you can dictate whether the damping effect is only present at the end positions or if it ensures even speed over the entire pivoting angle.

By avoiding sudden movements, the damper ensures that pipework, valves, and the actuator are intrinsically protected from mechanical stress.

No, the module is designed and constructed to be secure against manipulation, preventing unplanned changes to the settings.

A water surge (or water hammer) is a pressure wave caused by a fluid in motion being forced to stop suddenly; the damper prevents this by slowing down the valve closure.

No, the layout of the hydraulic damper is specifically designed to be compact to maintain a small footprint.

Compressed air is elastic; throttling air can lead to "stiction" or uneven speeds. The hydraulic medium provides a smooth, fluid resistance that air alone cannot achieve.

Yes, the damping module is designed to be compatible with the standard bar-agturn® series in both configurations.

Yes, the piston oscillates within a self-contained cylinder, ensuring the hydraulic medium stays within the module for long-term reliability.
