Summary:A tap particularly intended for dispensing of a beer, including low carbonated beer, incorporates an extension 9 downstream of the sealing member which does not restrict flow except when the tap is in the fully open position when the extension is drawn into a restricted portion 11 of the bore to produce a large pressure drop and creaming of the beer. Engagement of heel 16 in groove 18 defines an open position in which the extension is still located in enlarged portion 13 of the bore.
