The valve (1) has an one-chamber system with a retaining chamber in which a valve piston moves in longitudinal direction of the valve. A magnetic drive is provided for driving the valve piston, where the one-chamber system is made of a three-wall system. The three-wall system has an internal housing, an external housing (2) and a filling material inserted between the internal housing and the external housing, where the external housing takes over the function of a cooling element and the filling material is a resin. An independent claim is also included for a method for manufacturing an electromagnetic valve. Die Erfindung betrifft ein elektromagnetisches Ventil (1) insbesondere zur Verwendung in explosiven Atmosphären, umfassend ein Ein-Kammer-System mit einem Aufnahmeraum (9), in dem zumindest ein in Längsrichtung des Ventils (1) beweglicher Ventilkolben (6) und eine Magnetantrieb (5) zum Antrieb des Ventilkolbens aufgenommen sind, wobei das Ein-Kammer-System aus einem Drei-Wand-System (2, 4, 10) gebildet ist.
