my electric solenoid is heating up very very much, its like u cant even touch it. im worried about my cylinder heating up and might blow my safty valve breaking all my tanks as its kept behind the tanks. i also touched the cylinder tap and its quiet warm. can any1 also tell me how much heat can a co2 cylinder bear before breaking......

Google for the melting point of steel.
The whole length of the cylinder is not warmed by the solenoid, cannot happen.
You can hold the "cylinder tap" for hours, so the gas at the tap is not overheated by any stretch of imagination.
Everybody's solenoid heats up as much as yours. Rest easy.

CO2 TANK SAFETY – Using your Outback Air CO2 System:
. VERY IMPORTANT! Your Outback Air CO2 system was designed for use when sitting on its base and upright. It may be stored on its side or any other position when not in use. There is liquid CO2 in the tank when filled and you don’t want that coming out of the hose! You want to use the CO2 gas at the top of the cylinder.
. Open the tank valve completely when in use. Close the tank valve tightly for storage.
. Take care of your Outback Air CO2 system. It was designed for rugged outback use but the regulator and tank valve must be protected from damage. If you didn’t purchase one with your system, an Outback Air tank bracket will keep it safely secured until you need it.
. Your Outback Air CO2 system comes with a 150 psi static regulator. Be sure any air tool you may use has a maximum rating of 150 psi or greater. The actual usable pressure at the tool end of the coilhose is about 120 psi. Tools with a lower max psi rating can be used, but must not be run for long periods of time to avoid damage. Use your best judgment. Outback Equipped is NOT RESPONSIBLE for damage to tools you may use other than the air chuck supplied with your system at time of purchase.
CAUTION! – Please Read This Carefully!
. A CO2 cylinder is filled with liquid CO2 by weight. At the time of fill the temperature of the charge is extremely cold and the pressure is around 100 psi.
. When a fully charged CO2 cylinder warms up to room temperature (70 F), the pressure inside the cylinder increases to 837 psi.
. When the same cylinder reaches 87.9 F the entire charge becomes a gas no matter what the pressure. A fully charged CO2 cylinder at 87.9 F will have an internal pressure of approximately 1100 psi.
. At 120 F the same cylinder will have an internal pressure of nearly 2000 psi. This cylinder at 120 oF now has an internal pressure greater than the marked service pressure of a cylinder that is properly filled, not overfilled.
. At 155 F the same cylinder will reach a pressure of 3000 psi, a pressure great enough activate the safety vent on the valve, venting the CO2 charge.
. As you can see, when the temperature of the fully charged cylinder increases, the pressure increases. A temperature of 155 F, at which the safety would actuate and vent the contents of the cylinder, is not that high of a temperature. This temperature could easily be reached in many different environments (i.e. in a shed or a vehicle on a hot day, etc.). Unexpected venting of a cylinder through its safety can be startling to say the least, potentially leading to accidents, property damage, or personal injury. Coming into contact with the venting of the CO2 charge of a cylinder can cause personal injury such as frostbite.
When using, handling, transporting, and storing a CO2 cylinder always be aware of the temperature to which the cylinder will be exposed. This is not just the temperature the cylinder is exposed to at that point in time, but also the maximum temperature that the cylinder will be exposed to at any time in it's service. Outback Equipped, along with the CGA, recommends that CO2 cylinders not be used at temperatures exceeding 120 F.
