Abstract
A gas inlet valve with incompatible materials isolation is provided. The valve may include a piston that seals against a surface when in a closed position and that permits gas to flow through the valve and out the outlet port when in an open position. A bellows may protect the actuation mechanism of the piston from gas that may be present in the valve when the valve is in the open or closed position, and the piston may include a second seal interface that seals the bellows off from the gas flow area when the valve is in the open or closed position.
