The difference between electric proportional valve and solenoid valve

Valve control of flow can be divided into two types:
 

     One is switch control: either fully open or fully closed, the flow rate is either maximum or minimum, there is no intermediate state, such as ordinary electromagnetic through valve, electromagnetic reversing valve, electro-hydraulic reversing valve. The other is continuous control: the valve port can be opened according to the need of any degree of opening, thereby controlling the size of the flow through, such valves have manual control, such as throttle valves, but also electronically controlled, such as proportional valves, servo valves. So the purpose of using proportional valve or servo valve is: to achieve the flow control by electronic control (of course, after structural changes can also achieve pressure control, etc.), since it is throttling control, there must be energy loss, servo valve and other valves are different, its energy loss is greater, because it needs a certain flow to maintain the work of the pre-stage control oil circuit.
Electromagnetic valve (Electromagnetic valve) is the use of electromagnetic

   The controlled industrial equipment is an automatic basic component used to control the fluid, which belongs to the actuator and is not limited to hydraulic and pneumatic. Used in industrial control systems to adjust the direction of media, flow, speed and other parameters. The solenoid valve can be combined with different circuits to achieve the desired control, and the precision and flexibility of the control can be guaranteed. There are many kinds of solenoid valves, different solenoid valves play a role in different positions of the control system, the most commonly used are check valves, safety valves, direction control valves, speed regulating valves and so on.
