To control pneumatic cylinders and actuators with fluid power, air flow must be reliably controlled, typically with a Micro Solenoid Valve . Common Applications of the Solenoid Valve It is used in fluid power pneumatic and hydraulic systems, to control cylinders, fluid power motors, and larger industrial valves. Solenoid valves are used in factories/plants where compressed air is not available. In domestic washing machines and dishwashers, the solenoid valves are used to control water entry into the machine. A solenoid is also very important in the medical field especially when equipment have to be very precise and accurate; solenoid manufacturing for medical purposes has been of too strict standards since life is at stake. Solenoid valves can be used for a wide array of industrial applications, including general on-off control, calibration, pilot plant control loops, process control systems, and various original equipment manufacturer applications. Other solenoid operated valves used at a more advanced method varies in pressure, flow depending on the input signal. Working Principles of a Solenoid Valve When the Solenoid receives the electrical signal, a magnetic field is created, thereby causing two forces counter one another and channeling air directly to spring a plunger inside the coil, which has an integral seat to forcefully open when the solenoid coil is energized. Depending on the valve design, when electrical current is removed from the coil, a return spring brings the plunger back to the original closing state, thus cutting off the flow of the fluid.
