Cylinder completely produced by Alfatek, made of 304 stainless steel, complete with sight glass.
Consisting of a rectified and chrome-plated piston working in a stainless steel cylinder with static seal, (system called plunger piston). The predetermined volume is obtained from the piston which, sliding on a static seal, enters the cylinder. The cylinder is without a three-way valve.
A modulating valve, designed and manufactured by Alfatek, allows closure of the suction when the container is being filled.
The opening of the modulating valve is performed by the container, in the absence of which there is no filling. The modulating valve allows the product flow to be varied, slowing or increasing the filling speed as desired, depending on the type of container. For example, in narrow-neck containers, it is possible to slow filling in the final part while maintaining a high production. Moreover, since there are no mechanical movements and dynamic seals, maintenance is reduced over time, avoiding the problem of introducing air into the cylinder, allowing greater precision in volumes, greater than traditional machines and weight filling systems.
