Water pressure tanks are steel pressure and fiberwound tanks. 
The water well pressure tanks should be sized to allow adequate water draw down to prevent your water well pump from short cycling, which can shorten the life of the pump. Normal minimum run time should be 1 full minute between the well pump turning on and turning off. The air bladder in the water pressure tank is pre-charged, and is separated from the water. Depending on the pressure switch selected, the air pressure in the top of the pressure tank, before any water is added, should be set to 2 psi below the pressure switch cut-in pressure. The water being pumped into the well pressure tank will press up against the air bladder and compress the air, causing the water to pressurize making the pressure switch to turn off the well pump when the desired pressure has been attained. Likewise, when the water pressure drops in the water well pressure tank, to the pressure switch cut-in rating, the contacts will close and turn on the water well pump to pressurize the bladder water tank.

Standard water pressure tanks are normally used for drain back systems. These are systems where the water drains the line back to the well to prevent freezing, after every pumping cycle. These standard pressure tanks use a air volume control in the side of the tank, up about half way. The water line, when it drains back, will have air in the water line. The air volume control allows the air in the line to escape from the tank until the water level rises to the point that it pushes the control float closed. Once the float closes off the air escape hole, the pump pressurizes the water pressure tank to shut off the pump. A 2 hole check valve is used to allow air to come in through a snifter valve, which looks like the air valve on your tire, to allow the water to drain back to the well, where a drain back valve allows the water to drain back into the well.
