Solenoid valve product selection considerations, the first is the output requirements of the solenoid valve.

The main types of measurement of electromagnetic valve are gas and liquid and its temperature, viscosity, concentration, corrosion and so on.

Flow rate is the rate of flow of fluid through the valve, the main performance indicators of the valve.

Pressure (poor) is to overcome the power to overcome the valve, the same is also the main indicator of the valve.

Seal the relativity of valve leakage indicators can be used in unit time of the valve leakage as a unit, or in some cases more applicable to gas, with a certain volume of gas in sealed container within a certain period of time the pressure drop to represent.

Solenoid valve will be heating, load cycle or the maximum power, as well as the power and heat of the solenoid valve to determine the temperature rise of the solenoid valve. The temperature rise and the ambient temperature of the solenoid valve determine the required insulation temperature of the electromagnet.

Input solenoid valve of different current waveform, it will produce different modes of operation.

The actual application of the power supply type may have DC / AC, constant voltage power supply, constant current power supply, battery, dry battery, DC motor, capacitor, through a rectifier filter, voltage range, the maximum available current and other factors.

Electromagnetic valve drive circuit in the control of contacts to protect the electromagnetic valve drive control contacts may be the spark, wear and noise.

Can provide the following appropriate protection:

Resistance & capacitance method; method of inserting diodes.

Environmental conditions and life needs are important considerations in the selection of materials and surface treatment methods of electromagnetic valve.

Environmental factors include: temperature, humidity, magnetic field or electric field; gas, liquid and solid contamination or corrosion, shock and vibration, etc..
