GEMÜ is a leading worldwide industrial and process valve manufacturer, supplying customers in the pharmaceutical, food and biotech industries, the microelectronics segment, and general industrial applications. These include water treatment, the chemicals sector, mining, and plant and machinery construction. Our valves control and regulate both inert and corrosive / abrasive liquids, as well as gaseous media and steam. GEMÜ has six manufacturing centres throughout the world, employing over 850 people. The company sells its products via 12 subsidiaries and a large worldwide distributor network.
Progressive plant and process automation goes down to the lowest process level, the valves. GEMÜ supplies a large number of products for valve connection, control and regulation for modern plant and process control systems. Many of these products have field bus capabilities (AS-interface, Profibus DP, DeviceNet, ControlNet). In addition Gemü offers special products such as the first AS-interface controller in the world, GEMÜ 4112, that enables a direct connection to ProfibusDP / ControlNet. Measuring and monitoring systems for volumetric flow, pressure, temperature and level round out this range of products.
GEMÜ is the leading European manufacturer of aseptic diaphragm valves in stainless plant, DN 4-150. The valves are autoclavable, sterilisable, and designed for minimal deadleg. 2/2 way and multi-port bodies, T-valves, tank valves, and valve configurations are all available. The surface finishes according to customer wishes is down to 0.25m and electro-polished.
For the wide area of industrial applications GEMÜ offers an also wide range of valves: diaphragm valves in plastic and metal from DN 8-300, globe and control valves in plastic and metal from DN 3-150, butterfly valves in plastic and metal from DN 15-2000, ball valves in plastic and stainless plant, DN 8-100, solenoid valves in plastic and metal from DN 2-50 and pilot valves in metal and plastic from DN 1-7.
The production of semiconductors, flat screens and other microelectronic equipment requires special valves. GEMÜ is offering a complete range of for this industry. CleanStar, ultra pure valves in PFA-HP from DN 4-50 (1/4in to 2in), Pureplus, high-purity valves in PVDF-HP and PP-HP from DN 12-100 (1/2in to 4in), FlareStar, ultra pure fittings in PFA-HP from 1/4in to 1 1/4in, HydraLine, pressure measurement devices in PFA-HP from 1/4in to 1 1/4in and TubeStar, high purity PFA tubing from 1/4in to 1 1/4in.
To integrate the valves in plant-automation GEMÜ offers electro-pneumatic position and process controllers for linear and quarter turn valves, measurement systems for flow, pressure, temperature and level indication, pilot valves, combi switchboxes and electrical position indicators, optical position indicators, manual overrides and stroke limiters as well as products and accessories for field bus systems
GEMÜ valves can be used for inert, corrosive liquid and gaseous media and steam such as clean media like high purity water (water for injection, deionised water), highly viscous media such as slurry and foodstuff, contaminated and particulate media, solvents and chemicals, abrasive media and slurries The working temperatures might be up to a maximum of 600°C, the working pressures up to 63bar.
