A solenoid valve is an electromechanical valve for use with liquid or gas controlled by running or stopping an electric current through a solenoid, which is a coil of wire, thus changing the state of the valve. The operation of a solenoid valves is similar to that of a light switch, but typically controls the flow of air or water, whereas a light switch typically controls the flow of electricity. Solenoid valves may have two or more ports: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports. Multiple solenoid valves can be placed together on a manifold.

A common use for 2 way solenoid valves is in central heating. The solenoid valve are controlled by an electrical signal from the thermostat to regulate the flow of heated water to the heating elements within the occupied space. Such valves are particularly useful when multiple heating zones are fed by a single heat source. Commercially available solenoid valves for this purpose are often referred to as zone valves

The media controlled by the solenoid valve enters the valve through the inlet port (Part 2 in the illustration above). The media must flow through the orifice (9) before continuing into the outlet port (3). The orifice is closed and opened by the plunger (7).  
The valve pictured above is a normally-closed solenoid valves. Normally-closed valves use a spring (8) which presses the plunger tip against the opening of the orifice. The sealing material at the tip of the plunger keeps the media from entering the orifice, until the plunger is lifted up by an electromagnetic field created by the coil.

A valve is a device which can be used to control the flow of liquids, gases, and slurries. Also known as regulators, valves can be found in almost any situation: chances are that you are sitting within a few feet of a mechanical valve right now.
Pneumatic valves have come a long way since the development of the compressor over a century ago. Starting with large manual and mechanical valves, they migrated to individually wired electric solenoids and ultimately ended up with plug-into-the-base electronics allowing for a single multi-pin connector or fieldbus installation.

       The 4th china International Fluid Machinery Exhibition incorporating ,The 2th China International Valve Exhibition 2008 Was Successfully Held from October 28th to 30th at China International Exhibition Center in Beijing. In the opening ceremony of this exhibition, president of our association Mr Sui YongBin delivered a speech in the hope of holding a successful exhibition, an exhibition which will provide a platform for both domestic and overseas valve manufacturers and valve users to communicate and cooperate. The following is the picture of the opening ceremony of this exhibition.
       The 2th China International Valve Forum 2008 was successfully held on October 27th at Beijing HuaDu hotel, at the beginning of the forum, president of our association Mr sui delivered a speech, Secretary General Mr Song and valve expert Mr Zhang Zonglie presided over the forum. in this valve forum, a dozen of valve experts gave reports on new valve technologies and valve products, valve companies such as Finland Metso, Germany Auma, Russian Scientific & Industrial valve Association, French Velan, American Garlock etc, all introduced their new technologies and products invoking the great interests and enthusiasm of the audience.
