Poppet-Valve Systems

Poppet valve systems rely on a discrete valve element commonly described as a poppet, pin, or cup seal that rests against a seat to hold back compressed gas. The valve remains closed under the combined forces of spring pressure and chamber pressure. During the firing cycle, a hammer, striker, or pneumatic ram delivers a defined impulse that lifts the valve off its seat for a short interval, allowing gas to flow through the valve orifices toward the paintball.

Because the valve is normally closed and opens only under external force, poppet systems can maintain relatively high stored pressures upstream of the valve. Flow characteristics depend on seat design, orifice area, and the duration of valve opening. These variables influence gas efficiency, peak flow rates, and the shape of the pressure pulse that accelerates the paintball.

Shot characteristics in poppet valve architectures are associated with a distinct mechanical impulse, as the hammer or ram impacts the valve assembly. The resulting firing signature reflects both mechanical and gas dynamic contributions. In operational discussions, poppet systems are often contrasted with spool valve systems, but both apply the same general principles of regulated gas release and pressure control.
