A lubricant valve assembly comprising one manifold block unit and at least one valve element coupled with said manifold block unit. The valve element has only one measuring piston and one valving piston slidably disposed therein, and the manifold block unit has required numbers of inlets and outlets integrally therewith. Further, the manifold block unit is so constructed as to supply lubricant, introduced therein from a lubricant supply pump, to the individual valve elements coupled therewith and to receive measured quantities of lubricant from said respective valve elements and discharge the same to the points to be lubricated. Between the valve element and the manifold block unit is interposed a cross-porting structure, so that the lubricant discharged from a pair of outlet passageways of the valve element may be led to only one of the outlet passageways of said manifold block unit. Further, an adjusting rod to verify the operation of the measuring piston disposed in the valve element is fluid-tightly sealed by a sealing member which is made from polytetrafluoroethylene and hence the lubricant valve assembly is highly resistive to high temperatures.
