The difference between solenoid valve and electric valve
Solenoid valves and electric valves are two kinds of automatic valves commonly used in industrial automation control. Although they seem to have only one word difference, there are many different applications. Shenzhen famous valve engineers share technical experience with you to discuss electromagnetics. The difference between a valve and an electric valve:
1. The solenoid valve is magnetically attracted after the electromagnetic coil is energized. The pressure of the spring acts against the pressure of the spring to drive the spool. The structure is simple and it is an electromagnetic coil. The price is cheap, only the switch can be realized; the electric valve is driven by the motor to drive the valve stem to drive the valve core to move, and the electric valve is divided into (shut-off valve) and regulating valve. The shut-off valve is a two-position operation that is fully open and fully closed. The regulating valve is an electric valve on the upper device, and the valve is dynamically stabilized in one position by closed loop adjustment.
Second, the solenoid valve is an industrial device controlled by electromagnetic, is an automatic basic component used to control the fluid, belongs to the actuator, and is not limited to hydraulic and pneumatic. Used in industrial control systems to adjust the direction, flow, speed and other parameters of the media. The solenoid valve can be used with different circuits to achieve the desired control, while the precision and flexibility of the control can be guaranteed. There are many kinds of solenoid valves, and different solenoid valves play a role in different positions of the control system. The commonly used ones are check valves, safety valves, directional control valves, speed control valves, and the like.
Third, electric valve refers to the valve that is driven by the electric actuator or mediation . It can be divided into upper and lower parts, the upper part is the electric actuator and the lower part is the valve. There are two kinds of electric valves, one is the angular stroke electric valve: the electric actuator with the angular stroke is used with the valve of the angular stroke to realize the 90 degree internal rotation control of the pipe fluid on and off; the other is the linear electric valve: The straight-stroke electric actuator is used with a straight-stroke valve to achieve fluid on and off of the valve on-board action control. Usually used on a highly automated device.
Fourth, the use of electric valve and solenoid valve comparison:
Solenoid valve: Switch control for liquid and gas lines, is a two-DO control. Generally used for the control of small pipes.
Electric valve: Analog adjustment for pipe media flow in liquid, gas and wind systems, is AI control. In the control of large valves and wind systems, electric valves can also be used for two-position switch control.
Solenoid valve: can only be used as a switch quantity, is DO control, can only be used for small pipe control, common in DN50 and below pipes.
Electric valve: It can have AI feedback signal, which can be controlled by DO or AO. It is more common in large pipes and dampers.
Solenoid valves generally have a small flow coefficient. It is easier to be damaged by voltage shock. It is equivalent to the function of the switch, and the working pressure difference is small. For example, a general 25-caliber solenoid valve has a smaller flow coefficient than a 15-caliber electric ball valve. The solenoid valve is driven by an electromagnetic coil. It is the function of opening and closing.
