GEA Tuchenhagen VESTA® Sterile Valves engineering for a better world

Sterile Valves With its VESTA® sterile valve series, GEA Tuchenhagen offers the first practical, cost-effective alternative to diaphragm valves. The full benefits of VESTA® sterile valves, both technical and economic, have yet to be fully realised as new applications become apparent. VESTA® sterile valves fully meet the operational requirements for processes at the highest level, comply with the strictest safety regulations and provide a high quality product. High demands are placed on process components for the pharmaceutical, biotech, cosmetics and food industries if the highest process reliability...

Innovative, valve concept The VESTA® sterile valve from GEA Tuchenhagen now provides the market with a valve series which is suitable for applications from laboratory up to highly complex process plants. VESTA® sterile valves prevent product contamination from the outside, ensure that the process system stays free of germs. VESTA® sterile valve have the following design benefits: • Pocket-free design, without domes and sumps • PTFE bellows as shut-off element for universal applications • High service life of the PTFE bellows • A patented bellows sealing system hermetically, safely and permanently...

Sterile Valves Size – the deciding The VESTA® sterile valve series now makes these different sizes available for the different pipe standards. DIN – pipe standard DIN 11866, series A OD – pipe standard ASME BPE, series C ISO – pipe standard DIN EN ISO 1127, series B (larger sizes on request) The PTFE bellows – the heart of the valve The heart of the VESTA® sterile valve is the PTFE bellows made of TFM 1705. Apart from its outstanding chemical resistance to almost all types of media TFM 1705 is approved in accordance with the Code of Federal Regulations Title 21 § 177.1550 “Perfluorcarbon resins“...

Sterile Valves Actuators made of synthetic material and stainless steel – a real novelty GEA Tuchenhagen offers novel single-acting pneumatic actuators made of synthetic material for automated processes. The actuator system is made of the high-performance material PPS. This material has a good chemical resistance is temperature resistant up to 180 °C has good mechanical properties and is highly resistant to ageing. The actuator system is easy to maintain. Thanks to the special design, there is no risk of spring tension being relieved during dismantling. The actuator action is reversible, conversion...

Sterile Valves Optional equipment – full of variants The T.VIS® V-1 / V-20 is an electrical position indicator with feedback signals and optionally integrated solenoid valves. Automated end position programming can be activated alternatively using the buttons or the programming input (integrated as a standard) in just a few seconds. The T.VIS® P-1 / P-20 is a compact position controller for pneumatic valves. By specifying a setpoint (4-20 mA), transferred e.g. by the PLC, the process valve can be brought to any position. The position is detected by a position sensor with a resolution of 0.01...

Sterile Valves Surface quality – a important factor In sterile processes, the high quality of the surfaces is the basic requirement for a safe and reliable process. In product contact areas, VESTA® sterile valves generally have an inner surface roughness of Ra ≤ 0.8 mm (optionally electropolished). Higher-grade surfaces are available on request. VESTA® sterile valves are also suitable for use in cleanrooms. Reproducebility of manufacturing quality – another quality characteristic VESTA® sterile valves are produced in accordance with the highest quality standards. This is ensured by GEA Tuchenhagen’s...
