Clean solution for pure steam: GEMÜ 505 / 555
Video only available in German!
GEMÜ 505 (manually operated) and GEMÜ 555 (pneumatically operated) angle seat globe valves for isolating pure steam have been developed In close collaboration with a well-known customer from the pharmaceutical industry.
For reasons of quality, all wetted parts are made of high quality stainless steel (316L), while internally the valve body is actually mechanically machined clean and externally electropolished. With this surface finish, Ra values of up to 0.4 µm can be produced – and even reproduced – inside the valve body. In addition, the seal materials (seat code: 5P) satisfy the high FDA requirements and have been tested in accordance with USP class VI 121 °C.
As early as the creation stage of the user specification, particular requirements were defined for the production process and the maintenance of these angle seat globe valves. In particular, this included the creation of a traceability chain for all wetted parts. For this reason, valve bodies, retaining nut, seat, valve plug, spindle, bellows and actuator seal of the GEMÜ 555 and GEMÜ 505 are manufactured in specific batches and combined together in one production run. As a result, material test certificates in accordance with 3.1 DIN EN 10204 can be issued and supplied with the product if required.
At the Powtech and Technopharm 2013 trade fairs, the German technical journals "cav chemie anlagen verfahren", "dei – die ernährungsindustrie" and "Pharmaproduktion" conducted an interview with Peter Meyer on the topic of the new globe valve.
