Venturi type: CTF are used as an alternative to CRF rotary valves but have a lower capacity. Venturis are suitable for CTRL blowers type 20/40/55/75 and Multiair versions C1020, C1040, C1055 and C1075.

 

Rotary valves types: CAD, CAE, CRF20 and CRF40 are used for metering, vacuum conveying, dosing, pressure conveying and suction/pressure conveying.

 

Both models are suitable for vertical feed and with an additional connection, can be converted to horizontal feeding. The speeds are 70, 50, 30 or 20rpm (CRF20) and 70, 50 or 35 (CRF40) which are achieved by selecting different gear motor drives. Variable speeds can be achieved by the use of a variable frequency drive (inverter).
