Normal Close Type Water Valve 2V200-20


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.

Description of Water Solenoid Valve

Water solenoid valve has closed cavity, in a different location to open a hole, each hole leads to different tubing, cavity valve is among, both sides are two electromagnets, which face the magnet coil electricity body will be attracted to which side, by controlling the movement of the valve body blocked or leakage of different discharge of oil hole, and the oil hole is always open, hydraulic fluid will enter the different oil drain, and then through the oil pressure to push the cylinder piston, piston drives the piston rod, piston rod drive mechanism. Thus the mechanical motion is controlled by controlling the current of the electromagnet.


How to distinguish normally closed solenoid valve and normally open solenoid valve

General daily use of solenoid valve is divided into two types of normally closed and normally open, normally closed solenoid valve refers to the coil is not energized when the air circuit is broken, normally open solenoid valve refers to the coil is not energized when the air circuit is open. Normally closed type solenoid valve action principle: to the coil power, the air circuit is connected, once the coil power, the air circuit will be disconnected, this is equivalent to the point. Normally open type solenoid valve action principle: to the coil power, the air circuit is disconnected, once the coil power, the air circuit will be connected, this is the point. Usually according to the duration of the work to choose: normally closed, normally open, or sustainable power 1, when the solenoid valve needs a long time to open, and the duration of the time to close the excess time should be selected normally open type. 2. If the opening time is short or the opening and closing time is not long, then select the normally closed type. 3, but some conditions for safety protection, such as furnace, kiln flame monitoring, can not choose normally open, should choose long-term electrified type


The Working Principle of Normal Colse Type

Normally closed, when energized, the electromagnetic coil generates enough electromagnetic force to lift the moving parts (composed of magnetic core, valve stem, upper and lower diaphragm/seal) from the valve seat and open the valve; When the power spring force to the moving parts on the seat, the valve closed.
