Frequently Asked Questions About Hydraulic Actuators
Learn the answes to some of the most common questions about hydraulic valve actuation.
Hydraulic actuators are mechanical devices that convert hydraulic energy into mechanical energy to move valves and control the flow of gases or fluids in a system.
Hydraulic actuators are commonly used to automate valves on gas transmission pipelines, as the pipeline gas provides a ready source of power for the devices.
Some of the primary benefits of hydraulic actuators include:
- High torque/thrust output for operating large, heavy or high-pressure valves
- Highly accurate positioning for precise process control
- Fast response times to control signals, making them suitable for ESD and applications requiring fast valve actuation
- Robust designs for lower maintenance requirements and longer operational life
- Ability to incorporate fail-safe mechanisms in some designs, which allow the actuator to automatically return to a predetermined position in case of power loss or system malfunction
