Two position three-way solenoid valveInstructions:

The solenoid valve can operate in one direction (single solenoid coil design) or in two directions (two solenoid coil design), has a valve seat, and is suitable for connecting to a hook and loop connector or a threaded connection port from M5 to G1/2. It is designed as a two position two-way, two position three-way, two position four-way, two position five way, four position five way, and two position eight way valve. Like pneumatic drive valves, these valves have valve seats and can be configured in the control box.

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 isolation sleeve, without dynamic sealing, so external leakage is easily blocked. 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.

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.

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. (There are many new ideas trying to break through, but they are still in the experimental stage) Therefore, the adjustment accuracy is still 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.
