Garlock Butterfly Valves: Trusted throughout chemical, petrochemical and many other industriesSTERILE-SEALNo survival for bacteriaFor fermentation, sterile processing is the premise to guarantee the optimum productivity of the used microorganisms.All bacteria have to be destroyed before fermentation and also all products fed into the process have to be sterilized.Most important is the avoidance of any contamination during fermentation up to the separation of the biomass andtreatment of the final product.The new re-designed STERILE-SEAL valve with its steam blocking chambers surround and protect the product area againstexternal pollution, even under vacuum conditions. This design is a major breakthrough for large scale biotechnology plants.With the STERILE-SEAL valve bacteria contamination is a thing of the past.ConstructionThe media in the inner chamber isprotected against contamination bythe surrounding isolation chamberswhich are directly connected to theinner sealing system. A secondouter sealing system separates theprocess from the atmosphere.STERILE-SEAL valves are completelyvoid and cavity-free to prevent anybuild-up of nutrients.Operation PrinciplePressurized steam is fed into thesteam inlet and distributed throughthe longitudinal channels of the shaftand out through the flow control atthe bottom of the valve body. It isalso possible to seal the valve bypressuring the isolation chambersand closing the steam outlet connection.Sterilization ProofDuring tests, STERILE-SEAL valveswere contaminated at several pointswith Bacillus Stearothermophilus witha population of 5,7x105. Pressurizedsteam was then allowed to flowthrough the two chambers, followedby sterile air. In every instance thebacillus was completely destroyed.The safe conceptSTERILE-SEAL valves meet the highest standardsof Garlock’s excellence.For example:BodySplit-body, manufactured from ductile iron,cast steel or stainless steel.
