Dosing 3 positions
USE: Filling and dosing of fluids or half solids materials by means of a special metering device. Double acting actuator for fine or rough dosing.
CONSTRUCTION: The basic model consists of an Actuatech double acting actuator, equipped with two additional cylinders whose inner-pistons, by means of a stroke adjustment device, stop the rotating angle of the actuator to a pre-set position, preventing it from a complete rotation. Thanks to stroke adjustment device, the desired metering can range from 0° to 45°.

A. Fully closed position
In this position the air is supplied to port 4 with exhaust air at port 2 and 6. |
B. Fully open position
(90° rough metering) In this position the air is supplied to port 2 with exhaust air at port 4 and 6. |
C. Intermediate position
(fine metering) In this position the air is supplied to port 6 than to port 4, with exhaust air at port 2. In this case the external pistons will move to the desired rotating angle, consequently reducing the total valve flow. |
