How can I control the speed of my pneumatic actuator?
Adjusting the pressure may have an effect on the speed, but is not a recommended method to control the speed. To maintain a constant speed for your pneumatic actuator, size a fixed orifice for a constant flow on the exhaust port of the pneumatic actuator in conjunction with a pressure regulator on the input.
How does a flow control affect the actuator?
Many flow controls have a variable orifice size, so turning the adjustment counterclockwise will increase flow, while turning it clockwise will close the valve, limiting the flow and slowing down the actuator. Whenever a flow control is adjusted so that it limits flow, there will always be a pressure drop across the orifice.
Can a Lac Board control a linear actuator?
A linear actuator control board gives you control over an actuator’s speed, end-limits and sensitivity. It also gives you the option of controlling your actuator with one of five different input signals. An LAC board can only be used with Actuonix ‘P’ series micro linear actuators, as well as some large-scale actuators that have position feedback.
How to lower the speed of a linear actuator?
A simple way to lower the speed of a linear actuator is to reduce the voltage at which you drive it. The speed of Actuonix actuators is approximately proportional to voltage. This means that if you were to drive one of our 12V actuators at 6V, the speed would be roughly half of what it is a 12V.

How to change the direction of linear actuator?
In order to change the direction of movement of the linear actuator rod, it is necessary to change the direction of rotation of its motor. In the case of using a DC collector motor, it is enough to change the polarity of the supply.
How many turns does it take to change the speed of a hydraulic system?
A common number of turns between fully open and fully closed is five, so each full turn of the knob will change the orifice size by 20 percent. Manual valves such as ball valves, gate valves and butterfly valves should never be used to control speed in a hydraulic system. These types of valves are meant to be open or closed.
