Solenoid valve product selection considerations First of all, the output of the solenoid valve requirements. Solenoid valve to measure the fluid type is mainly gas and liquid and its temperature, viscosity, concentration, corrosion and so on. Flow rate refers to the speed of fluid flowing through the valve, the valve is the main performance indicators. Pressure (poor) is the force to be overcome when the valve is closed, the same is also the main indicator of the valve. Leakage is relative to the valve leakage index, you can use the unit of time the amount of leakage of the valve or, in some cases more suitable for gas, with a certain volume of gas in a sealed container pressure drop over time to indicate . When the solenoid valve is energized, it will generate heat, the load cycle or the maximum energized time, and the power and heat dissipation of the solenoid valve determine the temperature rise of the solenoid valve. Solenoid valve temperature and ambient temperature determines the level of insulation required for the material of the solenoid. Input different current waveform of solenoid valve, will produce different working mode. The actual application of the power type may be DC / AC, constant voltage power supply, constant current power supply, batteries, batteries, DC motors, capacitors, through a rectifier filter, voltage range, the maximum available current and other factors. Solenoid Valve Drive Circuit Protection of Control Contacts Solenoid actuated contacts can spark, wear, and create noise. Proper protection can be provided as follows: Resistive & Capacitive Methods; Methods for Inserting Diodes. Environmental conditions and life expectancy needs are important considerations in the choice of solenoid valve materials and surface treatment options. Environmental factors include: temperature, humidity, magnetic field or electric field; gas, liquid and solid pollution or corrosion, shock vibration and vibration.

All aluminum alloy material has strong plasticity and never rusts. Fluorocarbon baking powder is delicate, smooth, and long-lasting without fading. The product is intelligently matched with various smart devices, making it a minimalist, luxurious, and youthful fashion design style.
Advantages of aluminum doors:
Strong and durable: Aluminum alloy has high strength and hardness, can withstand the collision and wear in daily use, and has a long service life.
Corrosion resistance: Aluminum will naturally form an oxide film in the air. This oxide film can effectively prevent aluminum from further oxidation and corrosion, making it stable and not easily damaged in environments such as moisture, acid and alkali.
Good fire resistance: Aluminum alloy has good high temperature resistance, which can play a role in fire prevention to a certain extent and increase the safety of living.
Good sealing: Aluminum doors can be equipped with high-quality sealing strips to effectively improve the sealing performance of the door, and have significant sound insulation, heat insulation, and dustproof effects.
Various styles: Through different surface treatment processes and designs, a variety of colors and styles can be achieved to meet different decoration styles and personal preferences.
Environmental protection: Aluminum is a recyclable material and conforms to the concept of environmental protection.
