The Rütten Diaphragm valve line has been designed in order to tackle observed disadvantages of state-of-the art diaphragm valves currently used by the industry: diaphragm deformation (cold and during vapour-sterilisation), leakage due to misplaced diaphragm, leaching of toxic compounds from glued components, etc. These kinds of complications pose a serious threat to pharmaceutical production processes.

Rütten's design focuses on compacity and cleanability. The combination of requirement based engineering of valve body and diaphragm, paired with selected diaphragm materials, give way to a technically outstanding and user friendly valve. Its body, including nozzles, is machined out of one single piece and therefore exempt welding seams, in order to avoid undefined surfaces and corrosion. The valve is extremely compact and angled to allow total drain, ensuring perfect CIP and SIP results.
The diaphragms are made out of one molded piece and designed with a bulb-seal line. Both features increase valve tightness to a great extent. Fail-safe positionning of the diaphragm is ensured. The star knob and the valve spindle made of brass allow a particularly smooth turning. The closing force is adjustable with a torque wrench.
