As 2542 Flow liquid control solenoid valve For Medical Device

Working Principle of Liquid Control Solenoid Valve

Solenoid valve is converted electric energy into mechanical energy. The main purpose of liquid control solenoid valve is to regulate the movement of liquid and eradicate the need for an engineer to manually control the valve, which will save the application both time and money.

This liquid solenoid valve consists of two parts: a solenoid and the valve. The valve system is made up of two or more orifices/openings, whereas, the solenoid is home to several important parts, including a coil, sleeve assembly and plunger.
This solenoid valve works by current through solenoid copper coil to open or close the valve orifice. When the coil within the solenoid is power on, the plunger is lifted or lowered to open or close the orifice. This is what in turn controls flow, regulating the movement of liquid.

Disadvantages of this medical solenoid valve

Every valve has its own disadvantages. Due to human errors, solenoid valve can experience problem when the voltage becomes too less or too more due to this it makes the electromagnetic field strengthen or weaken.
1.Solenoid valve is sensitive to voltage
2.The valve can partly close if magnetic field isn’t set up correctly
3.The coil need to be replaced over the lifetime of the valve
4.Valve fluid can be affected by the flow.
