Abstract
Recently it has been shown that Torlon may be used to construct a rese alable superfluid bellows valve with a ''hard seat, soft stem'' config uration. We present a modification on this design incorporating a thin BeCu diaphragm to produce a valve having a dead volume of 0.02 cm(3) The valve may be actuated using a high pressure gas handling system or electrically using a sealed expansion volume.
