Abstract

The membrane valve has a heater which transmits heat to the valve spring (20). The valve has a casing (17) with an input line (21) and an output line (23). The induction line can be closed by a membrane (19) supported by the spring. The heating device may have a wall cladding (25) of a heat-conducting material such as copper, and a heating element (28).
