Abstract

A method for cleaning the seat of a double seat valve, the double set valve having a deflection surface bordering the remaining area of a recess not delimiting a circumferential wall and opening out from the latter at a front and radially inside end of a second closing member facing a first closing member. The method rinses the seating when closing members are opened and generates a seat cleaning flow and urges a first cleaning flow through a deflection surface.
