Abstract
A pinch valve that includes a holder and an insert that fits in the holder. The pinch valve receives a dispensing tube for liquids and controls the flow of liquid in the dispensing valve. The insert defines an inner wall portion against which a plunger assembly pushes the dispensing tube to stop liquid from flowing through the dispensing tube. The insert and the holder define a throttle portion that throttles the flow of liquid when the plunger assembly is moved from the pinch position, where is pushed the dispensing tube against the inner wall portion of the insert, to a flow position.
