Plastic solenoid valves are used for the release of steam and water. They come in low pressure releases as well. They range in many uses but are available for use to control water supply from the municipal source.
Reversing polarity ,changes the rotation of the device you are changing polarity on.
Its polarity is zero.CCl4 is non polar
The strength of polarity can be determined from looking at the level of polarity an object has. Polar bonds can make objects stronger or weaker.
no there is no consideration of positive or negative legs in case of resistor.
Solenoid valves are electromechanically operated valves which are controlled by an electric current, mostly used in fluidics. There are different types of solenoid valves, one or two port valves.

One can find information about plastic solenoid valves from a variety of places. Norgren, Reef Central, Danfoss, and GlobalSpec provide information about plastic solenoid valves.
Some times on/off valves are to large to be actuated using one solenoid valve,but most of the on/off valves are being actuated using only one solenoid valve
right hand rule is used to find out the polarity of current
Solenoid valves are used to stop, close, mix or distribute liquids. They are usually made from brass or aluminum and used in sprinklers, dishwashers or washing machines.
A direct acting solenoid valve is one in which the action of the solenoid alone switches the valve gate. Most solenoid valves are "piloted", which means that a relatively small solenoid valve is used to allow pressurized air to actuate the valve gate mechanism. Because the solenoid does all of the work in a direct acting valve, the solenoid must therefore be larger than that of a piloted valve in order to generate the switching force. Piloted solenoid valves have the advantage of being more compact and consuming less current than a direct acting solenoid valve. Direct acting solenoid valves are useful when switching low pressure fluids.
Solenoid valves, magnetic contactors, motors.
This is good enough, if you want to purchase general solenoid valves like 2 way, 3 way , 4 way solenoid valves but for generic products you can also serch the manufecturer site as http://www.valve-store.com is a distributer.
The solenoid is comprised of a coil, coretube, core and enclosure. These are designed to handle the most demanding fluid control applications.
