Modularity
The device has a modular design and can be supplied with different media connections (also customised)
and actuator versions depending on the application.
5.2
Design
The device consists of a pneumatically operated piston actuator with a return spring, a stainless steel
housing and a PTFE bellows. The bellows serves to separate the media.
The materials used and the internal contours allow easy cleaning (CIP/SIP).
The pneumatic actuator must be controlled externally with a pilot valve or a valve island.
