Arca’s MF0 actuator from the proven 812/813 series is a pneumatic actuator that was specially designed to be compatible with sterile and fine chemical applications. It is particularly well suited to the tight space requirements associated with prefabricated system components.
This diaphragm actuator is the first to integrate the fully welded construction of the actuator chamber as used on piston actuators in sterile process technology. The design facilitates very small dimensions and maintains a specified effective diaphragm surface of 143 cm2. To this end, the circular formation of bolts that affix the diaphragm in conventional diaphragm actuators has been eliminated to lend the actuator a smooth, easy-to-clean surface that is free of bolt heads and other sharp edges. The smooth surface also minimises the risk of injury when maintenance work is performed.
The new diaphragm joint and welding gap ensure that the surface pressure on the diaphragm is precisely defined and evenly distributed, and the low thermal influence exerted by the diffusion weld never impacts the diaphragm.
