Rotative & double-flap valves
The “double flap” valves
Device based on a casing with 2 flaps acted alternately to ensure an airlock isolation
The ratary valves “premium” series
Rotary valves for basic applications
The SAS rotary valve
Rotary valve is designed for small depressions isolation or dosing purpose
The “self-cleaning” rotary valve
This valve is specifically designed for sticky products purpose, and is equipped with synchronized additional cleaning rotor
