The valve has a housing (18) including an inlet (10) and an outlet (12). A valve seat including a valve opening (22) is arranged between the inlet and the outlet, where the seat has a sealing unit (20) with a sealing lip (34) adjacent to a valve body (26). The valve body is moved between opened and closed positions relative to the valve opening. An auxiliary sealing unit (48) lies in an inner area of the body, where a line contact is provided between the sealing unit and the body. A valve lifter (30) connected with the body moves the body between the opened and closed positions. |
