Direct Drive Type 2W Series Water Solenoid Valve 2W200-20 made of Brass

Direct-acting solenoid valve, when energized, the electromagnetic coil produces electromagnetic force to lift the closure from the valve seat, the valve open; When the power, the electromagnetic force disappeared, the spring to the closure of the pressure on the seat, the valve closed.

Working principles

This valve is the pilot type solenoid valve of the second opening valve. Its structure is mainly composed of the pilot valve and the main valve. The main valve adopts the rubber sealing structure. When in normal position, the guide valve is sealed with movable iron core, the pressure in the valve chamber is balanced, and the main valve is closed. When the coil is energized, electromagnetic force is generated to absorb the moving iron core, and the dielectric self-guiding valve mouth in the main valve cavity is discharged, resulting in pressure difference. The diaphragm or valve cup is quickly lifted, and the main valve mouth is opened, and the valve shows a path. When the coil power off, the magnetic field disappeared, the resetting of the active iron core, closed valve mouth, valve and the main valve chamber pressure balance, the valve was closed state

How to distinguish the normally closed solenoid valve, and, normal, open, type, electrical, magnetic valve,

No power valve for the path state is normally open, is closed state is normally closed. Working principle is to rely on the solenoid valve coil power supply magnetic force to drive the spool action to connect or disconnect the pipeline.

Normally open and normally closed are only switches, namely the two states of the relay. Normally open and normally closed can be set by themselves. For example, when the pressure value is lower than a certain value, it is normally open.

It can also be normally closed when the pressure value is lower than a certain value. When the pressure value is higher than this value, the switch action will make the normally closed state become normally open. It depends on how you set it up.

Two - way valve is usually open and often closed two kinds, but either solenoid valve, or manual valve, never seen two kinds of control, the valve will often open valve spool reverse assembly becomes normally closed.

Job purpose

Water solenoid valve is suitable for water or liquid as the working medium, can automatically control or remote control of water, oil, liquid and other working medium pipeline on and off. Because this valve USES the rubber seal, therefore to the working medium cleanliness greatly reduces, has opens and closes quickly, the reliability high characteristic.
