With a solenoid valve, it has become easier to automatically control the fluid flow in many equipment and plant. The electrically driven valve can be used for allowing or shutting off the flow of fluid. Through spring action, plunger or pivoted armature is pulled when the valve is energized to allow the fluid flow and returned to position when it is de-energized to restrict the fluid flow. In any system, there can be several solenoid valves placed together for regulating the fluid flow. Besides shutting off and releasing regulations, this kind of valve can also be used for dosing, distributing and mixing fluids. The main parts of this kind of valve are valve body, spring, orifice, lead wires, inlet & outlet ports, and coil winding. The kinds of this valve offered are port high pressure valve and pneumatic valve.
