Fluid Metering Assembly Overview

Electric Fluid Metering Assembly

The fluid metering assembly (Fig. 2) can be attached
to a robot arm, or mounted on a pedestal. Main com-
ponents of the fluid metering assembly are:
D PrecisionFlo metering valve (A )
D flow meter (B) to precisely measure the amount of
fluid dispensed and close the flow control loop
D solenoid air valve (C) that controls a dispense
device
D metering valve closer (D)
D solenoid air valve (E) that controls the metering
valve's closer

PrecisionFlo Metering Valve

The PrecisionFlo metering valve (Fig. 3) is a precision
fluid pressure regulator that uses a magnetic linear
servo motor to regulate material pressure and flow.
The needle assembly is directly connected to the linear
servo motor, so the needle responds immediately to
any motor movement.
