<p>A tap 10 comprises a valve body 14 and a valve mechanism. The body 14 defines a flow passage 22, an inlet opening 36, an outlet opening 38 and a valve seat 24 surrounding the inlet opening 36. The valve mechanism includes a valve member 16, a valve stem 18 connected to the valve member 16 and a valve actuation member 20. The valve body 14 is adapted for displaceably mounting the stem 18 and the valve member 16 to the body 14 and rotatably mounting the member 20 to the body 14. The member 20 defines an axis A of rotation about which the member 20 is rotated. The member 20 engages the valve stem 18 in an arrangement wherein rotation of the member 20 causes linear, non-rotational displacement of the valve member 16 along a displacement axis C extending transversely relative to the axis A, for displacing valve member 16 between an open position wherein the valve member 16 is spaced from the valve seat 24 and a closed position wherein the valve member 16 seats against the valve seat.</p> |
