Frequently Asked Questions About Hydraulic Actuators

Learn the answers to some of the most common questions about hydraulic valve actuation.

What is a hydraulic actuator?

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.

Where can you find hydraulic actuators?

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.

What are the benefits of hydraulic actuators?

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

Compressor Station Goes Green, No Functionality Compromise

An energy company wanted an actuator solution to stay ahead of environmental requirements while reducing the risk of unplanned maintenance and downtime.
