Gemü has released the Type 649 valve, specifically designed for controlling media with high purity requirements, such as aqua purificata, high purified water or water for injection, 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.
Using the electric actuator offers particular advantages in systems where no compressed air is available, in systems which are intended for mobile use or in systems where a cost-intensive supply of sterile air would be required.
In remote mode, the actuator can be operated using both standard signals (digital/analogue inputs/outputs) and via an interface with an integrated web browser (eSy-Web), which can be used to check and adapt the actuator data without additional software or link several actuators together. The energy supply to the actuator can be protected against power failures by an optional emergency power supply module. The Gemü 649 is additionally supplied with an integrated manual override, a mechanical position indicator and an electrical status and position indicator.
The nominal sizes DN 32, DN 40 and DN 50 will be available from the sales launch, while other sizes will be released over the course of the year.
