Sipa Introduces New Filling Valves

An important feature in the design of the valves is their modularity. The valves can be equipped with additional elements allowing HOT FILL applications with re-circulation or with Ultra Clean.

Aug 1 2011 --- Our continuing mission to find new and better-performing products led to the development of a new series of volumetric filling valves: ISOTRONIC SC for carbonated products and UNITRONIC SC for still products. These valves, replacing versions already present in the range, show new aspects that are absolutely state-of-the-art. Our goal: to go beyond the standard quality normally requested for this type of application.

In the development of the new generation of valves, the aim was to achieve higher quality and levels of efficiency, while maintaining the key features of the previous generation - simplicity and flexibility, high performance, ease of use and maintenance, and extreme cleanliness inside the system. Another main guideline of the project was to develop extremely versatile valves capable of satisfying the need to increase the quantity of products coming off the same bottling line. In fact both valves can modulate the filling speed to better suit the characteristics of the individual liquid product, avoiding turbulence, foaming and absorption of air into the product.

The valves are characterized by high dosing precision, thanks to the use of magnetic flow meters. The product deflection is provided by a swirling device.

An important feature in the design of the valves is their modularity. The valves can be equipped with additional elements allowing HOT FILL applications with re-circulation or with Ultra Clean.

Furthermore they are provided with features allowing the treatment of different bottle and neck sizes with much reduced change-over times. All valves are made in stainless steel 316L and are solid and compact. They have been designed so that there is a clear separation between the pneumatic parts and the parts in contact with the filling product, in order to avoid any problem with contamination.

Very simple machine management: each product/bottle size can be selected directly from the operator touch screen control panel.

Electronic and pneumatic components are enclosed in a special ring box located directly over the filling valve. The box is air-conditioned by a “vortex” system.

ISOTRONIC SC is the isobaric volumetric and electronic filling valve version, suitable for filling liquids with or without gas into PET bottles.

It is particularly suitable for filling liquids characterized by good conductivity, such as soft drinks, water and clear fruit juices. The bottles are held by the neck ring, no height adjustment of the machine is required and bottle sealing is guaranteed by a short stroke bottle lifter.

Special release of the filling valve provided with an additional system to control the internal recirculation of a product or the flushing phase in case of beer filling.

UNITRONIC SC is the gravitational volumetric and electronic filling valve version, suitable for filling non carbonated conductive products like still water, juice, tea, energy drinks and milk in PET bottles. This solution is extremely clean: there is zero contact between the valve and the bottle. Thanks to this feature, this version in particularly suitable for ULTRA CLEAN solutions.

Extreme cleanliness is one of the key points of this project: valves are very simple, product chambers do not come into contact with a single pneumatic part and, furthermore, in both the versions we have studied a dummy bottle activation system that is extremely simple and automatic, thanks to an innovative sliding solution. The sealing is guaranteed by a pneumatic rise of the bottle lifter. The dummy bottle has also been designed to keep the sanification recovery circuit inside.
