ABSTRACT:
A liquids dispensing valve comprising a cylindrical body (10) having a tapered outlet passage leading to an outlet orifice (12) at one end and an inlet orifice (30) at the other. Multiple pistons (18, 19, 20 and 21) depressed by springs (23, 24 and 25) progressively close the orifice (12). An air cylinder (14) with piston (16) progressively retracts the pistons (18, 19, 21) to open the valve and subsequently causes the valve to close progressively. Liquid flows downwardly through the ducts (28) in the valve in a generally axial or longitudinal direction and the subtended angle between the longitudinal axis of the body (10) and the wall of the tapered outlet passage is not more than 50.degree..
