An actuator is a type of instrument that is responsible for moving or controlling a mechanism or system. It is operated by a source of energy, It can be controlled mechanically, by  electric current, hydraulic fluid pressure, or pneumatic pressure, and converts that energy into motion. In my research, I found out that there are 5 types of actuators and these are the following. Mechanical Actuators In mechanical actuators normally a rotary motion is converted into linear motion to perform an operation. Such actuator normally involves gears, rails, pulley, chain etc to operate. Basic example of mechanical actuator is chain block hoisting weight […]

Since We started our pneumatic class on my third year in college, I already had the pleasure to meet this instrument. We even had to use this almost everyday, during our laboratory exercises. It’s always present in all our pneumatic and hydraulic trainers. How does this stuff really work?     A valve is a device that regulates the flow of fluid (gases, liquids,fluidized solids, or slurries) by opening and closing or partially obstructing passage ways.   A 5/2 way directional valve from the name […]
