Solenoid valves are available in different types to meet your project needs. Here we will introduce the 5 types of solenoid valves for your reference. Hope it could help you understand and know the valve deeply.
(1) Gas Solenoid Valve
Because of the adjustment of fuel structure in China, the proportion of gas fuel is increasing, and the demand of gas solenoid valve is also increasing. Gas has natural gas, industrial gas, city gas, liquefied petroleum gas and so on. Containing impurities and corrosion conditions vary, the valve requirements are not the same. Moreover, the pressure grade is very different, the compressed natural gas is as high as 21 ~ 25 MPa, and the gas pressure is as low as 2 KPa. There are mature products in our country.
(2) Steam Solenoid Valve
Steam solenoid valve first to solve the problem of high temperature, its sealing materials, conductive and magnetic materials to be specially selected. The corrosion of steam pipes is quite serious and must be taken seriously. What’s more, there is a lot of condensed water in the steam pipe after work. Solenoid valves need to be able to operate reliably when both gaseous and liquid fluids pass through.
(3) Water Solenoid Valve
Water solenoid valve is always considered to be the most simple, in fact, water is divided into tap water, industrial pure water, industrial waste water, irrigation water, sea water and many other categories, its corrosion performance, the degree of cleanliness is different, should choose different solenoid valve. Although the most common tap valve, but the use of different valve performance requirements are not the same.
For example, the electromagnetic valve for fire fighting, action reliability is very important, in case of failure can not imagine the consequences. Even if the ordinary manual valve does not open and close for a long time, it is difficult to open quickly. In recent years, high-rise buildings are springing up, China’s fire solenoid valve technology is also mature.
For example, water plants need to use the solenoid valve inverted siphon pipeline, this solenoid valve but in the pressure state, but also in the vacuum state to work reliably, must not have internal leakage, and the cleanliness of the water is not high, still should be flexible.
In addition, the spray irrigation solenoid valve has been gradually applied with the development of agriculture and garden industry in China.
(4) Solenoid Valve For Oil
There are many kinds of oil, and the seal technology is one of the key technologies. Oil-resistant rubber is only the name of the class, different oil or even the same oil containing different impurities need to choose different oil-resistant rubber. For example, resistance to leaded gasoline is not necessarily resistance to unleaded gasoline. In recent years with the increase in sales of special solenoid valve, special oil-resistant rubber life has been increasing.
Oil viscosity is very different, you have to choose a different structure of the solenoid valve.
High viscosity of the oil is often in the state of high temperature flow, so the solenoid valve is also necessary to solve the problem of high temperature. The fuel oil also needs to meet the explosion-proof requirements.
(5) Solenoid Valve For Air Conditioning
Air Conditioning is divided into heating and cooling. In recent years, obvious changes have taken place in refrigerants, ammonia and freon are gradually reduced, while new refrigerants such as lithium bromide are gradually increasing. It is worth mentioning that air conditioning mainly depends on the regulation of air volume to control temperature and humidity, valve flow of continuous regulation is not entirely necessary. Valveless air-conditioning systems are now in use, but problems such as condensation are to blame. Therefore, simple structure, low-cost solenoid valve is the best choice. Because of the influence of foreign tradition, the electric valve with complicated structure and difficult torque control is still widely used in China.
