Solenoid valve product selection considerations are first of all the output requirements of the solenoid valve.
The type of fluid measured by the solenoid valve is mainly gas and liquid and its temperature, viscosity, concentration, corrosivity and the like.
The flow rate refers to the speed at which the fluid flows through the valve and is the main performance indicator of the valve.
Pressure (difference) is the force to be overcome when the valve is closed, and is also the main indicator of the valve.
The sealing performance is relative to the leakage index of the valve. It can be expressed in units of leakage per unit time. Or, in some cases, it is more suitable for gas. It is expressed by the pressure drop of a certain volume of sealed gas in a certain period of time. .
When the solenoid valve is energized, it will generate heat. The duty cycle or maximum energization time, as well as the power and heat dissipation of the solenoid valve, determine the temperature rise of the solenoid valve.
The temperature rise of the solenoid valve and the ambient temperature determine the level of insulation temperature required for the electromagnet material.
Entering different current waveforms of the solenoid valve will result in different operating modes.
The types of power sources in practical applications may include DC/AC, constant voltage power, constant current power, battery, dry battery, DC engine, capacitor, through some kind of rectification and filtering, voltage variation range, maximum current supply and other factors.
The contact of the control contact in the solenoid drive circuit can be sparked, worn and noisy.
The following appropriate protections are available:
Resistance & Capacitance Method; method of inserting a diode.
Environmental conditions and life expectancy are important considerations in the choice of solenoid valve materials and surface treatment options.
Environmental factors include: temperature, humidity, magnetic or electric fields; gas, liquid and solid contamination or corrosion, shock and vibration.
