However, small volumes can only be controlled with an inadequate level of accuracy, or not at all. GEMÜ has now developed the GEMÜ 567 BioStarâ Aseptic Stainless Steel Control Valve in order to solve this problem.
Features and Benefits:
A 2/2-way globe valve with a regulating needle or regulating cone for high control accuracy and precise dosing.
The valve seat on both versions is sealed using a soft-seated seal.
The actuator is separated from the media-wetted area by an FDA-compliant PTFE diaphragm. This ensures a permanent, temperature-resistant seal and thus meets the high requirements of the pharmaceutical and food industries.
Compared with bellows valves, cleaning the valve is significantly improved by the hygienic and minimal deadleg design. It is likewise possible to clean and sterilise the valve using a CIP or SIP procedure.
The valve is also available with an integrated bypass so that the flow velocities required for the rest of the system can be achieved during the cleaning process.
GEMÜ 567 BioStarâ control can be integrated into a multi-port valve block, if required. This is another special feature of the valve, which not only requires considerably less space in the system, but also significantly reduces the installation and welding effort. All surfaces which come into contact with the product are precision-turned or polished.
Further, additional electropolishing can achieve a high surface quality of Ra 0.25 µm. EHEDG certification and testing in accordance with Procedure 3A are currently in preparation. The GEMÜ 567 BioStarâ control valve is available as an angled design in nominal sizes DN 8, DN 10 and DN 15.
Gemu Australia | Valves, Measurement & Control Systems
GEMÜ is one of the leading manufacturers of valves, measurement and control systems, and is the world market leader of valves for sterile applications in the pharmaceutical and biotechnology industries. This position was achieved following GEMÜ's comprehensive investments in application-specific research and development, amounting to more than 5 per cent of the company's turnover.
The level of innovation is closely linked to location - Germany is regarded globally as a nation of engineers. GEMÜ is over halfway up the chart of the top 1,000 German global market leaders for 2011. The GEMÜ headquarters is in the region that is home to the highest density of global market leaders, the region of Heilbronn-Franken in Baden-Württemberg. GEMÜ's international success is based essentially on the enterprise and pioneering spirit of Fritz Müller, who developed the world's first plastic process valve in 1964. This directly controlled solenoid valve was the starting point for the foundation of GEMÜ that year.
