<p>A liquid dispensing valve including a flexible length of tubing (20). The tubing is bent along two parallel lines (21A, 21B) transverse to the axis of the tubing (20). The tubing is held in an actuator (28) which, in a first position folds the tubing (20) along the two parallel lines (21A, 21B) to close the tubing (20) to the passage of fluid (12). In a second position the tubing (20) is partially straightened whereby fluid (12) can pass through the tubing (20).</p> |
