Description
The eco-PEN300 dispensing valve from preeflow offers a precision dispensing technology in a wide range of applications for low to high viscosity fluids and pastes.
Theory of function
The preeflow eco-PEN300 is a rotating and perfectly pressure-tight displacement system. The dispenser comprises of a self-sealing rotor and stator. Conveyance action by material displacement in the stator through controlled rotor rotation. Safe conveyance without any modification of the dosing material. With its suck back option, preeflow ensures clean and controlled material or medium cut-off while preventing post-dripping effects.
Other variants of the standard products are available on request, e.g. stator VisLas / drive train with rotor Diamond Coated / seals PTFE / housing stainless steel.
