Patented DVS Machines The SATE house revolutionized the conceptfor automatic dispensing system, when it introduced since 1995, the patented DVS Machine, than developped more and more during the years, to arrive to propose several different solution, all based on the patented DVS technologie:

The SATE patented dosing machines DVS:

• do not utilize valves manifolds, neither to select the chemical products to dose, nor to select the recipient machine

• do not require valves distributed in the whole plant in correspondece of each machine to serve with the chemical products, because the selection of the recipient machine is effected by the patented pratical revolvng selectro.

• Are equipped with an exclusive patented revolving selector that selects the product to dose avoiding in every case the contamination with any unrequested product. The two patented vectorial selector groups therefore guarantee the absolute separation both between the products and the machines.

• Utilizes special valves for the interception of the products, which operate in a simple and functional way; the valves of the products are placed in a round shaped formation, so that to guarantee a fast and safe selection of the desired product; moreover these valves allow the check of their seals in any moment from the outside of the machine, without the need to stop the dosing operations to open or dismantle any device.

•  The dosing machines "DVS" utilize inverter driven pumps which also have a suction function; this eliminates manny restrictions in the positioning of the chemical tanks, i. e. oblige the positioning of the tanks on a structure over the dosing station.

• The chemical products dosed by the DVS can be stored either in the original changeable tanks and/or in dedicated storage tanks. Moreover the DVS doses and distributes chemical products coming from a SATE modular group of automatic emulsifying tank or station.

All the dosing operations are managed by a SATE multitasking industrial computer that controls all machine functions, while executes a continuous check of the operations as well as a diagnostics routine. Dosing instructions can be imparted either by means of its keyboard or through a PC dedicated to the management, recording and remote control of dosing operations.

In this second case the whole system performs in real time the dosing operations, shows in real time the DVS status as well as dosing operations in progress and the products level in the tanks. The software also connects to centralized recipe and machine supervision software in order to receive and perform the dosing operations necessary for the execution of the programmed production processes.
