Beschreibung
Zusammenfassung:	An electromagnetic valve, especially for the control of low-temperature fluids such as cryogens, comprising an inner duct preferably of thermally nonconductive material or of a material weldable to the inner duct of a double-wall pipe line, a valve seat within the duct and a magnetically shiftable body movable within the duct into and out of engagement with the valve seat. The inner duct is spacedly surrounded by an outer duct which, in turn, may be surrounded by the electromagnet coil, the space between the ducts forming an insulator between the electromagnet and the valve members. This space is evacuated and/or filled with a thermally insulating material.
