ABSTRACT:
A liquid diluting and transfer valve assembly of a type which includes at least a pair of valve elements with slidably engageable surfaces which are frictionally movable relative to each other are provided with passageways therein in communication with liquids and diluents which are to be measured and transferred by the assembly. The valve assembly includes measure conduits which are arranged for selective communication with the passageways in the valve elements with the junctions of the measuring conduits and the passageways taking place at the engaged surfaces of the valve elements. This valve assembly is provided with an enclosure which completely surrounds and encloses the valve elements. The environment in the enclosure is controlled in order to inhibit evaporation and or dilute seepage of the fluids between the slidably engaged surfaces of the valve elements in order to prevent a buildup of contamination resulting in greater liquid leakage, wear and tear breakdown in the valve assembly.
