These metering valve distributors are used if an infinitely variable adjustment of the flow rate per lube point is required-even at a later date.
In the case of type A – for flow rates within the drop-feed range – knurled lock nuts and knurled screws are provided for adjustment purposes.
It is necessary to provide for a sufficiently large drain-off in order to maintain a free fall of drops in the sight-glass.
In the case of types B and C, the continuous flow rate is adjusted after the upper hexagonal lock nut is loosened. Spring-loaded metal pins in sight glasses indicate that oil is flowing when they move away from the mark.
