With type 649, GEMÜ is launching a motorized diaphragm valve for sterile and hygienic applications.
The valve was designed specifically for controlling media with high purity requirements, such as aqua purificata (AP), high purified water (HPW) or water for injection (WFI), in compliance with the regulatory codes of the pharmaceutical industry and the food and drink industry, and will be available in nominal sizes from DN 6 to DN 150.
With actuating speeds of up to 6 mm/s (depending on the actuator size), GEMÜ is expanding the range of and offering an alternative to the existing pneumatically driven GEMÜ 650 and GEMÜ 660 (filling valve) diaphragm valves with an even more precise control characteristic of ±0.1%. The tried and tested and EHEDG-certified seal system is also used.
The DC motor is based on the hollow shaft principle. Since the motor operates with no brushes and commutation is performed without sensors, the motor parts do not wear. At the same time, a compact design could be implemented, meaning that the valve can be compared to pneumatic actuators and an additional control assembly.
