Three way machine two three way solenoid valve is divided into normally closed and normally open two types, normally closed refers to the coil is not energized when the gas road is broken, normally open refers to the coil is not energized when the gas road is through.

Normally closed two three-way solenoid valve action principle: to the coil is energized, the gas circuit is connected, once the coil power, the gas circuit will be disconnected, which is equivalent to the "point".Normally open two three-way single electrically controlled solenoid valve action principle: to the coil, the gas circuit is disconnected, once the coil power, the gas circuit will be connected, this is also the "point".Two five-way double electrically controlled solenoid valve action principle: to the positive action coil is energized, then the positive action gas path is connected (the positive action air outlet hole has gas), even if the positive action coil power is still connected to the positive action gas path, will always be maintained to resist the coil energized stop.If the resistance coil is energized, the resistance gas circuit is connected (the resistance gas hole is energized). Even after the resistance coil is energized, the resistance gas circuit is still connected and will remain energized until the positive action coil is energized and stopped.This amounts to "self-locking".Three - way machine two - way solenoid valve is usually one in two out of the series.There is also a saying that often open often closed.Solenoid valve three ports are ABC three ports, usually A to B port or A to C port, there are B to C port.Normally closed type is the solenoid valve power off in the future, the valve is closed, normally closed.In other words, it cannot exit port A.

The main control system of the three-way machine is PLC control system. The three-way machine has an independent electrical control cabinet, and the main operation button is suspended on the fuselage.

The company mainly produces various types of three-way machine, elbow machine, pipe bending machine, pipe expanding machine, press, bevel machine, the above pipe fittings of the equipment supporting mold and other welcome the need of customers to consult and order!
