This question gets asked all the time.
You can use a solenoid valve to directly meter the flow of gas.

THe simple reason is that they do not have NEARLY enough flow capacity to handle the ball. Thats why all paintguns use wither a poppet or spool-based system.

That said, there is confusion above about what a SOLENOID is, and what a SOLENOID VALVE is.

A SOLENOID is a simple electromechanical device that produces LINEAR motion. Basically, it can either PUSH or PULL, and thats it. Like the electric door locks on your car.

A SOLENOID VALVE is a solenoid, like above, combined with a 4-way valve (or 2-way,3-way, etc). A 4-way valve is a device that controls airflow, usually to a ram, so control ram movement.

Many solenoid valves used in paintball are a special type called a "Piloted Solenoid Valve". THis have increased speed by using the solenoid to control a "pilot valve", which is like a mini- on/off, that controls a mini-ram, which then controls the primary 4-way. Sounds confusings, but it produces better performance.

^^^^ thnx for the explaination but i figured tht those tiny valves wouldnt move enuff air fast enuf. and where can i buy a spool valve or poppet?
thnx

You've got that one backwards. Piloted valves are slower, but use substantially less power than direct acting. Direct acting is faster, but needs a lot more juice to run.

ok so then hjow does a wrath work?. it take the air from the front then when u hit the awitch it lets air pass to the back. but how does the noid move enuff air to push the ram so fast and hard?

Christ man, read a ****ing manual or watch some animations. It works exactly the same way that any ram operated poppet valve gun does. Here's a flow chart to help you: Air enters ASA from tank -> From the ASA, air enters the HPR (high pressure regulator) -> from the regulator, regulated air enters the valve chamber (a large reservoir behind the poppet valve) where a portion of it is channeled to the LPR (low pressure regulator) -> from the LPR, regulated air enters the solenoid valve -> From the solenoid valve, air will go one of a couple places. By default, it will travel to the front of the ram so that the ram shaft retracts. Attached to the ram shaft is the hammer, and attached to the hammer is the bolt. So the entire assembly retracts - opening the breech so that a ball can load -> When the solenoid receives power from the board, the electromagnet will activate and cause the shaft inside the solenoid valve to shift. This will close off the vent to the front of the ram, vent the air from that channel out of the 'noid, and allow air to enter the vent to the back of the ram -> this shift will cause the ram shaft to fly forward, carrying the bolt and hammer with it -> the hammer will strike the valve, releasing air into the breech. At the same time, the bolt will have sealed the breech, and the air escaping from the valve will be channeled out of the bolt and onto the paintball, forcing it down the barrel.

ok ok i watched them. i guess low presure air is enuff to push the ram and bolt to hit the valve held shut with high pressure.

YES! That's the entire purpose of the ram. Imagine a blowback spyder, and replace the main spring with an air-controlled ram. Now you understand how a poppet valve, ram driven electro works.

it was baffleing cuz when i hear low pressure i think like 50-150 but really isnt it like 700?

No, low pressure really is in the lower range you mentioned. Try standing against something sturdy and pushing it. That is trying to open a valve with low pressure without the ram moving forward (already in the forward position). Now get a 50 foot head start and haul *** before throwing yourself against it, that is low pressure opening the valve with momentum thrown in (ram starting at back, building speed before hitting the pin on the valve). It gets a lot more done than just the pressure by itself. And if you feel the need to see this for yourself, bring a friend with a video camera, I'm sure we would all enjoy it

oooo so it uses momentum with the low pressure...wow i never thot paintball guns were tht good at being soo consistent.

why else you would think guns like spyders have a heavy ram? you use a small force(sping in spyder, air in timmy) to push a heavy object(striker in spyder, ram in timmy) with very little friction(the reason you have to use lube rams and strikers) to push open a valve held with high force.

the way alot of poeple explained it in here made it seem more consifung, but that's all it is.

Exactly. Like it has been suggested several times now, go here, and just stare at these for several hours, you should learn a lot.

Damn, I guess I haven't seen an Ion recently enough to remember right. Where does the air flow from when the gun is at rest?
