Product Portfolio

  • Our innovations

      • GEMÜ D40

      • The pneumatically operated GEMÜ D40 diaphragm valve is designed for use in sterile applications. The diaphragm hermetically separates the actuator from the working medium. All actuator parts (except the seals and design elements) are made from stainless steel. The "Normally closed", "Normally open" and "Double acting" control functions are available. The valve has an optical position indicator with a transparent cap as standard.

        Features:

        • For use in hygienic and aseptic applications (CIP/SIP capable and autoclavable)
        • Valve can be configured for the respective process parameters
        • Fast, safe and simple diaphragm and actuator mounting
        • Low maintenance due to the firmly chambered diaphragm
        • Very high Kv values thanks to the flow-optimized valve body
        • Identification of the angle of rotation (hash mark), optical position indicator and transparent cap as standard
        • Simple modular expansion possible thanks to state-of-the-art automation components

         

      • GEMÜ Multiport SUMONDO

      • If you are looking for Single-Use application components, GEMÜ is the right partner for you. We advise customers, design and produce our standard product range, as well as creating individual solutions on a case by case basis

        GEMÜ Multiport SUMONDO – Single-Use diaphragm valves in the smallest of spaces

        Combine several Single-Use diaphragm valves in a Multiport-block and reduce deadlegs and space while also saving on installation work. When designing the GEMÜ Multiport SUMONDO solution, we take your individual process requirements into account.

      • GEMÜ Q50 eSyStep

      • The GEMÜ Q50 eSyStep 2/2-way pinch valve is motorized. The eSyStep electric actuator is available as ON/OFF or with integrated positioner. The valve guides a tube which is compressed from above by a compressor to control and regulate media. The compressor's specially developed contour and the tube holder's contour minimize the strain on the tube and thus increase the tubes' service life. Tubes can be safely inserted and removed in simple steps and without tools. An optical and electrical position indicator is integrated as standard.

        Features:

        • Open/close function or with integrated positioner
        • Linear or modified equal-percentage control characteristics
        • Parameterizable via IO-Link
        • On-site or remote end position programming via programming input
        • Fast, safe tube replacement
        • Simple replacement of inserts and compressors for various tube sizes with the same actuator
        • Minimized strain on the tube due to the optimized compressor
        • Several installation options possible in the plant thanks to the mounting flange or female thread on the body

              • GEMÜ positioners and process controllers

              • GEMÜ's product range for process automation of valves includes three-point controllers to control the position of motorized valves and electro-pneumatic positioners for pneumatic valves with quarter turn or linear actuators. 

                In-house development

                The positioners are easy to initialize and all have the speed-AP function developed by GEMÜ. Time consuming manual setting is no longer necessary as the positioners are optimally adjusted to all valves. 

                Adaptation to different actuators

                Appropriate travel sensors enable easy mounting to other valve actuators and positioners can even be remote mounted.

                Motorized actuators

                GEMÜ offers several valve series with motorized actuators. These actuators are comparable with the electro-pneumatic positioners in terms of their functionality. They are available with both integrated positioner and combined position and process controller.
