Abstract

A regulating valve for a heat-transferring medium has a valve member controllable primarily by an electrical actuating member, but in the event of failure of the electrical actuating member, a thermostatic actuating member, operating independently of the electrical actuating member and of electric power, is provided in order to prevent damage to the system by driving the valve member when a predetermined temperature is exceeded.
