Typical setup for a 3/4 way 2 position way valve

How to setup a 3/4 way 2 position way valve?   1. To actuate one single-acting cylinder. Either oil port “A” or “B” must be plugged on valve. With port “B” plugged, solenoid is energized to position “A,” oil port “A” becomes pressurized. When solenoid is energized to position “B,” oil port “A” becomes the return port. 2. To actuate two single-acting cylinder. A pressure line from one bank can be connected to oil port “A” and the other to oil port “B” on the valve. Sequence: When energized to position “A,” oil port “A” becomes pressurized and clamps the fixture […]

Direct Operated 3/2 Way Solenoid Valves

A 3/2 way solenoid valve has three ports and two switching states. In each switching state, two of the three ports are connected. By activating the solenoid, the valve switches state and a different connection between the valve ports is established.   3/2 Way Direct Acting solenoid valves utilizes the armature movement as the direct means to the Open / Close the inlet or exhaust ports of the solenoid valve. 3/2 way normally closed solenoid valve Inlet pressure is typically through P1, so when the solenoid valve de-energized the inlet port P1 is closed i.e. the armature is down and sealing […]

5/2 way directional valve in a diagram

Example of using a 5/2 way directional valve as shown in a diagram Drawing below shows a double solenoid operated 5/2 way directional valve connected to a double acting cylinder/ with to proximity switch. the system is in idle condition.       When the start button is pressed momentarily. the cycle begins at logic 2 triggering EXT_B_SV solenoid which extends the cylinder. As soon as the proximity switch B_OUT is reached. Logic 3 comes in triggering RET_B_SV solenoid to retract the cylinder to its normal position.   When the push button is permanently pressed. The logic will flow continuously extending and retracting […]

What is an Actuator?

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 […]

How does a 5/2 way directional valve work?

5/2 way directional valve working principle.      This instrument is not new to me. 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 […]
