Valve - Difference Analysis of Oil and Water Solenoid Valves
Solenoid valve for oil: There are many types of oil, seal technology is one of the key. Oil-resistant rubber is just a category name. Different oils and even impurities in the same kind of oil require different oil-resistant rubbers.
For example, leaded gasoline is not necessarily resistant to unleaded gasoline. In recent years, with the increase in the sales of special electromagnetic valves, the lifespan of special oil-resistant rubber has also increased. The viscosity of the oil varies greatly and solenoid valves of different structures must be used. High-viscosity oils also often circulate at high temperatures, so electromagnetic valves also have to solve the problem of high temperatures. For fuel oil, it must also meet explosion-proof requirements.
Solenoid valve for water: The solenoid valve for water is always regarded as the simplest. In reality, the water is divided into tap water, industrial pure water, industrial waste water, irrigation water, and seawater. The corrosion performance and the degree of cleanliness are different. Select different solenoid valves. Although the tap water valve is the most common but has different uses, the valve performance requirements are different.
For example, the electromagnetic valve for fire fighting is very important in terms of operational reliability, and in case of failure, the consequences can be disastrous. Even if an ordinary manual valve does not open and close for a long period of time, it is difficult to open it quickly. In recent years, high-rise buildings have mushroomed, and China's fire-fighting electromagnetic valve technology has also matured. For another example, the water plant needs to use solenoid valves for inverted siphon circuits. However, this type of solenoid valve must be operated under pressure in a pressure state and must work reliably in a vacuum state. It must not have internal leakage, and the condition of clean water is not high. Next, it should still be flexible. In addition, the sprinkler solenoid valve also gradually applied along with the development of China's agriculture and gardening industry.
