The main features of the 4V310-10 explosion-proof solenoid valve are:
(1) External leakage is blocked, internal leakage is easy to control, and safe to use. Internal and external leakage is a factor that endangers safety. Other self-control valves usually extend the valve stem and control the rotation or movement of the valve core through electric, pneumatic, or hydraulic actuators. All of this needs to solve the problem of long-term leakage of valve stem seals; Only solenoid valves use electromagnetic force to seal the iron core inside the magnetic sleeve of the electric control valve, without dynamic sealing, so external leakage is prone to blockage. Electric valve torque control is not easy, which can easily cause internal leakage and even break the valve stem head; The structural type of solenoid valve is easy to control internal leakage until it is reduced to zero. So, the use of solenoid valves is particularly safe, especially suitable for corrosive, toxic, or high and low temperature media. Action express, with minimal power and lightweight appearance. The response time of solenoid valves can be as short as a few milliseconds, and even pilot operated solenoid valves can be controlled within tens of milliseconds. Due to its self-contained circuit, it responds more sensitively than other self-control valves. A well-designed solenoid valve coil has low power consumption and is considered an energy-saving product; It can also automatically maintain the valve position by triggering the action, without consuming any electricity during normal operation. The electromagnetic valve has a small external size, which saves space and is lightweight and beautiful.
(2) The adjustment accuracy is limited and the applicable medium is restricted. Electromagnetic valves usually have only two states: on/off, and the valve core can only be in two extreme positions, which cannot be continuously adjusted, so the adjustment accuracy is also limited to a certain extent. Electromagnetic valves have high requirements for the cleanliness of the medium, and are not suitable for media containing particles. If impurities are present, they must be filtered out first. In addition, viscous media are not suitable, and the viscosity range of media suitable for specific products is relatively narrow.
(3) The system is simple, easy to connect to a computer, and the price is affordable. The solenoid valve itself has a simple structure and low price, making it easier to install and maintain compared to other types of actuators such as regulating valves. More significantly, the composed self-control system is much simpler and priced much lower. Due to the fact that the solenoid valve is controlled by switch signals, it is very convenient to connect with industrial control computers. In today's era of widespread computer use and significant price reductions, the advantages of solenoid valves are even more apparent.
(4) External leakage is blocked, internal leakage is easy to control, and safe to use. Internal and external leakage is a factor that endangers safety.
