Electrical proportional valves can be divided into two types of flow control.One is the switch control, one is continuous control,servo valve and other valves are different, its energy loss is greater, because it needs a certain amount of flow to maintain the pre-stage control oil work.One is the switch control: either fully open, or fully closed, flow or maximum, or minimum, no intermediate state, such as the ordinary solenoid through valve, solenoid directional valve, electro-hydraulic directional valve.The other is continuous control: the valve mouth can be opened according to the needs of any opening, so as to control the flow through the size, this kind of valve has manual control, such as throttle valve, also have electric control, such as proportional valve, servo valve.The electric proportional valve controls the gas pressure through the electric signal, which can realize the continuous and stepless adjustment of the gas pressure, and can realize the remote control and program control.

Introduction to electric proportional valve:
DFL electric proportional valve is based on the size of the control signal to adjust the valve core section area. So as to achievethe goal and requirement of adjusting the flow rate.
Electrical proportional valves can be divided into two types of flow control.One is the switch control, one is continuous control,servo valve and other valves are different, its energy loss is greater, because it needs a certain amount of flow to maintain the pre-stage control oil work.One is the switch control: either fully open, or fully closed, flow or maximum, or minimum, no intermediate state, such as the ordinary solenoid through valve, solenoid directional valve, electro-hydraulic directional valve.The other is continuous control: the valve mouth can be opened according to the needs of any opening, so as to control the flow through the size, this kind of valve has manual control, such as throttle valve, also have electric control, such as proportional valve, servo valve.The electric proportional valve controls the gas pressure through the electric signal, which can realize the continuous and stepless adjustment of the gas pressure, and can realize the remote control and program control.
