The main features of AirTAC

(1) External leakage is blocked, internal leakage is easy to control, and it is safe to use. Internal and external leakage is a safety hazard. Other automatic control valves usually extend the valve stem, and the rotation or movement of the valve core is controlled by electric, pneumatic, or hydraulic actuators. This must solve the problem of external leakage of the dynamic seal of the valve stem during long-term operation;only the solenoid valve uses electromagnetic force to act on the iron core sealed in the magnetic isolation sleeve of the electric regulating valve. There is no dynamic seal, so the external leakage is easy to be blocked. . It is difficult to control the torque of electric valves, and it is easy to cause internal leakage and even break the valve stem head;the structure of the solenoid valve makes it easy to control internal leakage until it drops to zero. Therefore, solenoid valves are particularly safe to use and are especially suitable for corrosive, toxic or high and low temperature media.
(2) The system is simple, easy to connect to a computer, and the price is low. The solenoid valve itself has a simple structure and low price. It is easier to install and maintain than other types of actuators such as control valves. What is more significant is that the automatic control system is much simpler and the price is much lower. Since the solenoid valve is controlled by a switch signal, it is very convenient to connect to the industrial control computer. In today's era when computers are popularized and prices have dropped significantly, the advantages of solenoid valves are even more obvious.
(3) The action is fast, the power is small, and the appearance is lightweight. The response time of the solenoid valve can be as short as a few milliseconds, and even the pilot solenoid valve can be controlled within tens of milliseconds. Due to its self-contained loop, it is more responsive than other automatic control valves. A properly designed solenoid valve coil has very low power consumption and is an energy-saving product;it can also automatically maintain the valve position by simply triggering the action, and does not consume any power at all. The solenoid valve has a small appearance and size, which not only saves space, but also is light and beautiful.
(4) The adjustment accuracy is limited and the applicable medium is limited. Solenoid valves usually only have two states: on and off. The valve core can only be in two extreme positions and cannot be continuously adjusted. (There are many new ideas trying to break through, but they are still in the trial stage.) Therefore, the adjustment accuracy is still limited. The solenoid valve has high requirements for the cleanliness of the medium. Medium containing granular particles cannot be used. If it is an impurity, it must be filtered out first. In addition, viscous media cannot be used, and the viscosity range of media suitable for specific products is relatively narrow. (5) Various models and wide range of uses. Although solenoid valves have inherent shortcomings, their advantages are still very prominent, so they are designed into a variety of products to meet various needs and have extremely wide uses. The progress of solenoid valve technology also revolves around how to overcome inherent shortcomings and how to better utilize inherent advantages. AIRTAC solenoid valve is an automation basic component used to control the direction of fluid. It is an actuator. It is usually used on mechanical control and industrial valves to control the direction of the medium, thereby controlling the valve switch. Working Principle: There is a closed cavity in the solenoid valve, with through holes at different positions. Each hole leads to a different oil pipe. There is a valve in the middle of the cavity, and two electromagnets on both sides. Which side of the magnet coil is energized and the valve body will Wherever it is attracted, different oil drain holes are blocked or leaked by controlling the movement of the valve body. While the oil inlet hole is normally open, the hydraulic oil will enter the different oil drain pipes, and then push the cylinder through the pressure of the oil. The piston drives the piston rod, and the piston rod drives the mechanical device. In this way, the mechanical movement is controlled by controlling the current on and off of the electromagnet.
