What are the advantages of solenoid valves?

Solenoid valves are used as an actuator for mechanical instruments. The main advantages apply to:

1) In addition to safety, leakage is blocked, and leakage is easy to control. Leaking up and down is an element that compromises safety. Other self-control valves generally open the valve stem, and the electric vehicle, pneumatic, hydraulic actuators control the rotation or travel of the valve core. All of these must overcome the leakage and leakage of the valve stem seal in the long-term posture; the solenoid valve is completed with the magnetic core of the DC magnetic activity in the borehole of the magnetic field, and the dynamic seal is never applied, so the external leakage is not easy to block. The electric valve torque is easy to control, it is difficult to cause internal leakage, and the stem of the valve stem is broken. The structure of the solenoid valve is difficult to control within the control, until it drops to zero. Therefore, solenoid valves are particularly safe, and are particularly limited to toxic, highly toxic or high temperature fluids.

    2) The device is intuitive, it is connected to the computer, and the price is high. The solenoid valve itself is intuitive in construction and high in price. It is not easy to install and protect other actuators such as regulating valves. It is becoming more and more obvious that the self-control device is intuitive and the price is higher. Because the solenoid valve is controlled by the power pulse, it is very convenient to connect with the industrial computer. With the popularity of computers today and the rising price, the disadvantages of solenoid valves are even more pronounced.

    3) The voltage is small, the appearance is small, and the posture is fast. The solenoid valve call-up time can be as long as a few seconds, even the first-lead solenoid valve can be controlled within tens of milliseconds. Because of the self-contained circuit, the chemical reaction of other self-controlled valves is becoming more and more acute. The designer's proper electromagnetic field valve coil has a very high power loss, which is an energy-saving product. It can also realize the posture only, manually maintain the valve position, and never consume power at all. The solenoid valve has a large outer shape, which not only saves dimensions, but also is small and durable.

    4) Various models for universal use. Designers come in a wide variety of products that meet a variety of different needs and are used in general.

 DC magnetic valves are also quite reasonable, with more than the shortcomings, the lack of application above a certain level: regulation accuracy limitations, limited fluid limitations. Solenoid valves generally only have two conditions of power supply, the valve core can be in two speeds of light, and must not be controlled by time interval, so the regulation accuracy is also subject to certain constraints. Solenoid valves have relatively low recommendations for fluid cleanliness. Fluids containing granules must not be limited. If they are oxides, they must be filtered first. In addition, viscous fluids are by no means limited, so the specific product-limited fluid viscosity area is quite narrow. However, with the change of technology, the advantages of the solenoid valve will gradually increase.
