Product Overview
The GEMU 640 15D 034132 0 is a pneumatically actuated diaphragm valve engineered by GEMÜ (Gebrüder Müller Apparatebau) for precise, contamination-free control of aggressive and high-purity media in industrial process systems. Operating on a linear pneumatic piston actuator principle, the valve isolates the working fluid from the actuator mechanism via a flexible diaphragm, eliminating packing glands, stem seals, and dead pockets where media could stagnate. The 15D body configuration provides a nominal line size of DN 15 with a robust plastic or metal body construction suited to corrosive service. This valve functions as a critical shut-off and control element in hydraulic and pneumatic process circuits, delivering bubble-tight sealing, high cycle life, and reliable performance in chemical, water treatment, and pharmaceutical process lines.
