GEA VESTA® Sterile valves are part of GEA’s extensive aseptic valve technology portfolio. These valve lines are characterized by their hermetic sealing concept. The VESTA® Valve line is based on PTFE bellows technology, making it ideally suited to applications in the pharmaceutical, biotech, and cosmetics industries. Thanks to the hermetic sealing of the valve stem by a single-piece PTFE bellows, VESTA® Sterile valves reliably separate product-wetted areas from the environment and thus significantly enhance process and product safety. The valve line, which is based on a seat concept, also boasts optimized flow and dead-space-free valve housing.
An unbeatable advantage over conventional membrane valves is the easy service of VESTA® valves. The maintenance of a VESTA® valve is about ten times faster and saves the manufacturer an enormous amount of time while increasing production availability.
The core component of VESTA® Sterile valves is their single-piece PTFE bellows, which is made from the material TFM 1705. The patented bellows sealing system safely separates the product-wetted area from the atmosphere in all process steps and seals the valve seat.
Adding to its excellent chemical resistance against almost all media, TFM 1705 also complies with all standards relevant for the pharmaceutical industry, including FDA 21 CFR 177.1550 and USP class VI. The high-quality surface finish (Ra≤ 0.8 μm), the seamless and hermetic sealing as well as the CIP/SIP optimized design are further distinguishing features.
Their safe and easy handling means VESTA® Sterile valves can be quickly assembled/disassembled, significantly enhancing the efficiency of routine checks and maintenance. VESTA® Sterile valves have no loose parts and all maintenance work can be carried out using standard tools. PTFE bellows showing no wear during routine checks can be re-used without hesitation.
Essentially, a bellows unit includes all of the valve wear parts that come into contact with the product, as well as the components required to replace the unit quickly.
