About JOYNER pneumatic
JOYNER pneumatic GmbH has been a manufacturer of pneumatic cylinders and pneumatic valves since 1993, headquartered in Korntal-Münchingen near Stuttgart. Originating from the merger of the sales partners of Knorr Industriepneumatik, the company covers all stages of the value chain, from development through manufacturing to sales. In addition to a broad standard range of cylinders, valves, K-rings, linear actuators and accessories, JOYNER realizes custom pneumatic special devices such as telescopic cylinders, valve assemblies and cylinder-valve units. The portfolio includes standard cylinders to ISO 15552, ISO 6432 and ISO 21287 in aluminium and stainless steel (1.4404, AISI 304), as well as magnetic, hand-lever, plunger, roller-lever, NAMUR, low-temperature and Ex valves. A special field is the spare parts service for the KNORR pneumatic series worldwide. Customers come from industrial automation, the process industry and valve automation, commercial and rail vehicles, agriculture, the food industry, medical technology, paper machinery and shipbuilding. The pneumatic manufacturing has been continuously certified to ISO 9001 since 1995 and takes place in European plants, primarily at the Erkrath site near Düsseldorf.
