The valve block systems on the tapping point and on the sampling bottle have an EHEDG diaphragm sealing system made from FDA-compliant materials. Due to the multi-way solution, this system is both sterilisable and autoclave-capable.
The valve body is made from stainless steel (1.4435 or 1.4435 with a ferrite content under 0.5 per cent), glass or stainless steel can be used as the bottle material.
The bottles can either be provided separately or supplied as an overall package (stainless steel bottle 1.4404, Schott Duran Pressure plus glass bottle). The maximum capacity in the GEMÜ sampling bottle system is 1000 ml. As standard, the seals are made from PTFE, EPDM or FEP; other materials are available on request.
As standard, the valve bodies enable the following functions:
Pneumatic or manual operator
Sampling connection and CIP/SIP inlet
Due to the flexibility in the design of GEMÜ block systems, these functions can be offered with different geometries. Other functions can also be integrated on request.
The complete sampling path can be sterilised easily before sampling
Microbiologically flawless sampling via a closed system
Connection to existing lines can be easily implemented
Compact and variable due to multi-port valve block solution with various forms of construction

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.
