BOTTLE MAKING 20 PET planet insider Vol. 16 No. 04/15 www.petpla.net Strong airflow with small valves Eugen Seitz AG is working with modern product equipment Sometimes it is the small things that make the life of a beverage line operator easier. This definitely applies to reliable and long-life blow- ing valves in the stretch blow moulding machines. We spoke to Mr. Francesco Fini, Business Unit Manager PET, Eugen Seitz AG Switzerland. Eugen Seitz has been manufac- turing solenoid valves for gaseous media in the medium and high-pres- sure range for over 50 years. In the mid 1990s, the company was asked by leading stretch-blow moulding machine manufacturers whether Seitz could also make solenoid blowing valves to replace cam-driven mechan- ically actuated valves. Seitz accepted the challenge and designed a first dedicated solenoid operated blow- ing valve which enabled the machine manufacturers to boost their bottle output considerably. Since those days Seitz is now in a leading position in the field of blow- ing valve technology for stretch blow moulding machines. Every second PET bottle in the world is produced with a Seitz valve. Today the minimum performance requirements for blowing solutions are minimal dead volume, fast, accurate and repeatable valve switching times and maintenance friendly design. It is all about keep- ing the TCO value and consequently bottle production cost of the blower as low as possible. Seitz call themselves “the perfect development partner” offering extensive and appropriate expertise delivering tailored high-end solutions. Modern technical infrastructure, the latest simulation tools, a labora- tory able to reproduce an entire cus- tomer defined stretch blow moulding process allows technical and life span validation prior to product delivery. The Seitz products range consists of Single Valves, Blowing Blocks, Blowing Units (Cylinder-Valve Com- bination) and, unique in the market, integrated Blowing Stations combining Cylinder-Valve Combination and Elec- trical Stretching Unit. www.seitz.ch Mr. Francesco Fini, Business Unit Manager PET
