Abstract
A pressure valve for heating a pressure medium and maintaining its temperature constant, has a control slider provided with a throttle, a pilot valve influencing a position of the control slider and having a spring-loaded valve member and a valve seat, a thermosensor arranged to sense the pressure medium and to determine throttling of the latter, wherein the thermosensor controls an electromagnet acting upon the pilot valve, and the spring of the pilot valve in the opened position of the valve member is at least partially pretensioned, and upon actuation of the electromagnet and assuming by the valve member the closed position the spring is tensioned to a value corresponding an opening pressure.
