Zusammenfassung:	A body member formed as a solid block of high purity iron is provided with an axial bore forming a fluid inlet passage and a planar end wall surrounding the bore. The valve member which blocks the inlet flow also is shaped as a solid block formed of high purity iron. Further, this latter member is slidably carried in a casing and itself has a planar end wall adapted to flushly engage the end wall of the valve body member and, when so engaged, to block the inlet flow. The body member carries an electric coil to magnetize the high purity iron pieces and cause the valve member to move into its flow-blocking position. When the coil is not energized, fluid flow admitted through the axial bore spreads laterally and forces the valve member away from the valve body member to create a gap in the order of 0.010 inch. This small stable gap allows closure of the valve with very low electrical power.
