The invention discloses a tap (10) for controlling liquid flow. The tap (10) has a tube (14) with first (16) and second (18) opposite open ends, an inlet opening (20) leading into the tube between the first and second open ends, and an outlet opening (16) defined by the first open end (16), which outlet opening (16) serves as an outlet from the tube (14). The tap (10) further includes a first valve seat (36), formed between the inlet opening (20) and the outlet opening (16), and a second valve seat (38), formed between the inlet opening (20) and the second open end (18). A closure member (42) is sealingly slidably movable in the tube (14) and is provided with a first circumferential sealing edge (60), the first sealing edge (60) being adapted to removably abut against the first valve seat (36). The closure member (42) is further provided with a second circumferential sealing edge (66), the second sealing edge (66) being adapted to removably abut against the second valve seat (38).
