Something About a Solenoid Control Valve
Referring to the literal meaning of a solenoid control valve, the core part of this mechanism would be the solenoid. And it is true that the solenoid actuator control the valve to regulate certain fluids or gases. The electrical current through a solenoid signifies a lot. Thus, this mechanism can be classified into the electromagnetic valves.
Considering about the suitable media, a great variety is available, especially for the fluids. In most cases, a solenoid control valve is designed and applied into releasing, distributing or mixing different fluids. In fact, it is expected that this mechanism would turn the electrical energy into mechanical energy. Then, it is possible for the relative valve open and control mechanically. Just considering about the ability to convert, the metal seal is resulted to be more popular and functional. Besides, it should be mentioned that a spring is used to hold the valve open or closed under the inactivated condition.
In the following, a simple and clear introduction to the operation of most solenoid control valves is given. At the beginning, the mechanism is placed in a closed state. The required fluid begins to enter an elastic diaphragm. The power caused by the flow of water would push the elastic diaphragm down. In fact, there is a pinhole in the centre of the diaphragm, which allows the fluid to go through. Once the pressure on both sides is the same, the force would, more or less, higher on the upper side. Therefore, such force is gained to shut off the incoming pressure, leading to the shut off of any water flow. At this moment, the significant solenoid coil would take effects. Once activated, the pin would be forced upside. Then, the required water flows through the conduit, go on to flow onto the output side of the valve. Eventually, the gained pressure pushes to drop and lift the diaphragm's main valve to let the flow go through. It is indeed the complete process of the entire operation. Most importantly, this process is rather environmentally undertaken. In words, all valves are doing their best to the development of both industry and society.

How a control valve with 3-15 psi pressure stops a flow of 100 kg/cm2 pressure?
I have the different concepts about this phenomenon that either positioner controls the movement of stem of valve or positioner just allow the flow of air using 3-15 psi as a signal. How a 3 - 15 psi pressure air can stop a flow of 100 kg/cm2 of any line.
It is usually done by a diaphragm operated by the 3 to 15 psi signal and in some cases the 3 to 15 pound signal activates a positioner that applies a greater pressure to assure the valve acts as required. The presence of a positioner is all part of the design of the system. Most valve manufacturers have specific guide lines as to when you should add a positioner to the system.
