There are many uses of valves - mainly controlling the flow of fluids and pressure.
When you search for solenoid valve 220v and related items, you will be able to find many types of solenoid valve 220v varying in size, shape, use, and quality, all at prices in which are highly reasonable! The normally-closed 2-position and 3-way pneumatic solenoid valve means that the gas circuit is off when the coil is not powered on (the inlet and the outlet are shut off), or that A and P are disconnected with power off, A and T are connected with power on.Searching for tools to control the flow of your piping system?

Working principle of the normally-closed 3/2-way pneumatic solenoid valve The coil voltage grade generally adopts DC 12V, DC 24V, AC 110V, AC 220V, etc. The 3/2-way pneumatic solenoid valve is usually used together with the single-acting pneumatic actuator, and adopts the single electric control, namely the single coil. The 2-position and 3-port pneumatic solenoid valve can be divided into the normally-closed mode and the normally-open mode. To the gas circuit or the liquid circuit, the two-position and three-port solenoid valve has one inlet (connected with the inlet air supply), one outlet (providing gas for target equipment), one exhaust vent (generally installed with a silencer, and if noises do not matter, the exhaust vent can also be uninstalled). As to the other two ports, one port is connected with the inlet port of the actuating element and another is connected with the exhaust port of the actuating element. Generally conditions, one port is connected with the air supply.
The three-port means that the valve body of the pneumatic solenoid valve has three ports, namely A, P and T, of which one (P) is for inlet and two (A & T) are for outlet (one of the outlet is normally-open and the other is normally-closed).
It means that the valve core controls different gas passages when the solenoid valve gains power and losses power. The two-position here refers to two different working positions (on, off) of the pneumatic solenoid valve core. The two-position and three-way (3/2-way) pneumatic solenoid valve is equipped with three air ports on two positions.
