marco technologies in focus: sJet

marco valves stand for precise dispensing results. Piezo components change their properties under continuous load. Thermal expansion, ageing and drift all play a role. To compensate for these factors, marco has developed SuperiorJet technology, sJet for short. The unique sJet valve control allows the opening and closing edges of the movement cycle to be individually adjusted to the requirement. The closing speed, the closing curve or a partial opening of the valve have an effect on the dispensing result in many applications. With sJet, for the first time it is possible to precisely determine how far, how fast and with how much force the valve tappet is moved. Deviations are automatically compensated and feedback is sent to the control computer in real time. This leads to constantly stable dispensing processes with both low and high viscosity media.
