The trend towards simplified upstream and downstream plant designs and the effective prevention of cross-contamination risks means that single-use disposable technology is becoming an increasingly high-profile and important field – especially in pharmaceutical process engineering and pilot project management.
The connection between the valve and the actuator is designed in a way that, after the application process, only the valve body is removed, while the actuator itself can be reused repeatedly in the plant.
The valve body is manufactured from polypropylene is gamma-sterilizable up to 50 kGy, and isolates the working medium hermetically from the environment and from the actuator via a diaphragm. The same internally welded diaphragm protects the medium from the environment not only during operation, but also after removal of the valve body.
The manually operated version has an optical position indicator as standard, and a new actuator has been developed, made of high-grade plastic, gamma-sterilizable and washable as well.
An autoclavable version is planned for the first six months of 2017.
