Do You Know the Specifications of Different Models of Normally Open Solenoid Valves?

Normally open solenoid valves still have great demand in the current valve market, and since the demand for this aspect is also different in various devices, there are a large number of models and qualities available for customization when choosing. This issue mainly briefly explains the specification classification and takes a simple look at the specific content in this regard.

1. Common specifications of normally open solenoid valves include the following:

(1) 3-position 5-way normally open solenoid valve: five ports, single electronic control of two positions: only one coil, which drives the valve core after being energized, and pushes the valve body back to its original position through a spring after power is cut off. (Usually, without breathing, without breathing, it will not affect the instrument.) A representative example is different 2-way 2-position solenoid valve models, and the overall effect is very good.

(2) Five ports, two positions, two coils: when one coil is energized, the valve core moves to one side; when power is cut off, the valve core remains in its original position until the other coil is energized, and only then does the valve core move to the other end. (Commonly used for mechanical crossing, continuous operation, and mechanical purposes.) Note that some of them are quite special, such as the 4V series solenoid valve coil.

(3) Gas-use 2-way 2-position solenoid valve: 2-position center-closed double electronic control: two coils; after one is energized it drives the valve core, and when power is cut off the valve core returns to the middle position; after the other coil is energized, it switches to the other end. (Commonly used for mechanisms such as mechanical crossing, continuous motion, and anti-fall.)

(4) Three ports, two positions, single electronic control: when a circuit breaker is opened, the power is disconnected, and it is disconnected when power is cut off (usually used for vacuum chucks).

2. Key application points of solenoid valves

(1) By operating the manual button, when the solar one-way solenoid valve is not energized, the solenoid valve can be switched on and off with the air passage. It is generally used in circuit debugging, maintenance, fault analysis, and so on. Press the manual button to open the air passage, and it returns to its original state after release.

(2) In addition to a single type of solenoid valve, there is also a method of centrally assembling two or more single valve bodies, namely the manifold type. Its characteristics are a compact structure and neat wiring.
