GEMÜ - Valves, Actuators and Control Systems

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.

PLANT AND PROCESS AUTOMATION

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.

ASEPTIC VALVES FOR PHARMACEUTICAL, FOOD AND BIOTECH INDUSTRIES

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.
