Born from a need for an aseptic valve to use in a single-use plant, GEMÜ has developed the world's first single-use diaphragm valve - GEMÜ SUMONDO.
The diaphragm valve body is easily connected and disconnected from the actuator. The diaphragm is ultrasonically welded within the body which then hermetically separates the working medium from the environment and the actuator. The medium remains closed o? from the environment by the internal welded diaphragm not only during operation, but also after removing the valve body. The body materials are cleanroom produced by GEMÜ and double bagged. When built into tubing assemblies they can be sterilised through gamma irradiation and GEMÜ SUMONDO is therefore flowpath ready.
GEMÜ SUMONDO has a panel mount actuator that remains in the plant ready for the next batch with optional positioner for flow control. Using a tried and tested actuator design from GEMÜ aseptic valves, the actuator can also transmit feedback as required to ensure complete monitoring of the controlled system. A SUMONDO version with a mini GEMÜ 1434 digital positioner lets the process modulate the flows through the valve using a PLC and 4-20mA control, making the GEMÜ SUMONDO even more versatile. pharmaceutical processes in particular will be made easier to document, reproduce and validate thanks to the ability to send feedback to the plant control system. The increased levels of automation also mean that the systems are less susceptible to faults. As the world’s first single-use diaphragm valve, GEMÜ SUMONDO is a major step forward in single-use applications.
