Solenoid valve in a closed chamber, in different locations with holes, each hole leads to a different pipeline, the middle valve chamber, two is two electromagnets, which face the magnet coil is energized the Valves will be attracted to either side, by controlling the body's movement to a different file live or leaked oil discharge hole, and into the hole is always open, hydraulic fluid will enter a different row of tubing, then through the oil pressure to push oil just the piston, the piston and drive the piston rod drive mechanism moving. This current through the control solenoid to control the mechanical movement.

Voice coil actuators, once used in radio have today emerged as popular options to be used in demanding applications like semiconductor equipment, defense systems and life-sustaining medical systems. They are actually used in places where proportional or tight servo control is very essential. Read on to know about the various operating principles of these tools.The voice coil actuators are nothing but the technical manifestation of the Lorentz force principle, according to which "power current carrying windings of electrical conductivity is directly proportional to the strength of the magnetic field and current." In this case, the current directions of the actuators are two-way i.e. similar behavior in both directions. An alternation in the current direction in one way alters the direction in the other way, which offers similar behavior in both directions. Both rotary and linear actuators are available in the market today.

Electronic voice coil motors on the other hand are single-phase motors and can be used as a conventional DC motors. A great advantage over the proportional solenoids, it is known for having very low hysteresis, which makes the voice coil actuators ideal for applications in both directions. In addition, the requirements of the noise level, small overshoot and very good handling, the force controllability too can be easily met with these coils.Voice coil actuators motors are known for providing very low hysteresis, cogging less performance, high dynamic response due to the small moving mass and capacity for high overload. In medical and such other applications, the voice coil motors are often supplied as pure actuators, where control of feedback is derived from other variables in the application, such as pressure or gas mixture in valves etc.Nowadays, there are a huge number of actuator manufacturers available in the market. You can even fulfill your requirements from them online. These suppliers are equipped to meet the needs of a varied range of clients that order from integration of components into their applications. This also includes customized solutions for all your coil actuator needs.Source: Micro solenoid valve, Pneumatic component
