Hydraulic Actuator

A hydraulic actuator comes in a number of piston types, designs and is very common for those applications that require loads of force for operating the valve. The movement of a hydraulic actuator is controlled by changes made in the amount of hydraulic liquid that is inside it. Earlier people utilized water as hydraulic liquid, but with the development in the filed of chemical engineering, now special oils have been designed, which are used for this specific purpose. When pressure is exerted on one end of a hydraulic actuator, then the fluid increases the pressure manifold and then converts it into mechanical movement. This is the mechanism, which helps these actuators in generating great power.
