ABSTRACT:
The body (1) of a valve of the invention is welded in the bottom vat (2) in which it constitutes a controlled orifice (5), which orifice is closable by means of a resilient membrane (3) driven by means of a control wheel (11). A complementary orifice (6) is provided at the lowest point of the internal cavity (8) in the valve body to enable the cavity (8) to be emptied completely under gravity. A duct (7) separate from the complementary orifice and open to an internal cavity enables the cavity (8) to be sterilized continuously. The invention is particularly applicable to the food industry.
