Needle dispensing valves can be a cost-effective alternative, but they do not offer particularly high dosing accuracy. Since they rely on pressure and time control, they are susceptible to fluctuations in dispensing volume, especially with changes in temperature or viscosity.

 

• Suitable for media with low to medium viscosity.

• Simple design and cost-effective solution.

• Limited precision due to pressure-dependent dosing.

 

For applications that require the highest dosing accuracy and process reliability, volumetric dispensing systems such as cartridge spindle valves, gear pumps, and eccentric screw pumps are the better choice.
