Standard systems for complex control tasks

manufacturers of valves, measurement and control systems. Over the course of more than 50 years, this globally focused, independent family owned enterprise has established itself in important industrial sectors thanks to its innovative products and customised solutions for process media control. Manufacturing is carried out at six manu- facturing sites in Germany, Switzerland, China, Brazil, France and the USA. A broad based modular system and adapted auto- mation components mean that individu- alised standard products and customised solutions can be combined to make over 400 000 product versions.

At present, control valves are increasingly becoming the focus of a wide variety of ap- plications. In order to provide the customer with a simple selection guide, GEMÜ has now summarised all the relevant compo- nents of a control system under the term Process Control System, or PCS. The PCS type combines the standard GEMÜ control valves with mounting kit, piping system and positioner. In this way, the customer has the option of ordering the appropriate control system and all the necessary components quickly and without error. Each nominal size has two regulat- ing cones (linear and equal-percentage) to choose from as standard. The operators for the GEMÜ 554 (plas- tic), GEMÜ 514 (aluminium) and GEMÜ 550 (stainless steel) series are available in the form of actuators. GEMÜ 1434, 1435 and 1436 have been integrated into the PCS as controllers. The standard versions of each controller are regarded as basic versions. The GEMÜ 514, 530, 532, 534, 550 and 554 series contain the nominal size range of DN 15 to DN 50. The GEMÜ 536 globe valve covers the nominal size range of DN 65 to DN 150. GEMÜ is one of the world’s leading
