SS needle valve

The chemical dosing percentage must be set on the stainless needle valves

The top nuts are screwed off by means of an adjustable wrench and the concentration can be adjusted.


One should hereby aim at opening the two needle valves equally. If necessary, a fine adjustment can be made on one of the dosing valves.

The adjustment of the valve is individual.

Dosage is dependent on many factors such as product temperature, viscosity, density, pressure conditions, lenght of hose, air pressure etc.

We  recommend that dosage is adjusted by your chemical supplier.

As soon as the requested concentration has been reached, the top nuts must be reassembled.
