Filling: The valve is in the initial position when the control pressure applied on the compressed-air connection. The valve needle in the control valve is in the upper position, thus  closing the material outlet. The material access  to the metering chamber is open. The material  enters the control valve by means of the  material pressure and lows into the metering    chamber. Due to the contact surface of the   piston, the piston executes an upward stroke.  The metering chamber ills up automatically to the pre-deined volume.

Metering: Material is metered when the  compressed air connection of the valve is   charged with compressed air. The valve needle  executes a downward stroke, thus closing the  material access to the metering chamber. The  material outlet opens. The material pressure has an efect on the piston step, which enters the  metering chamber and feeds the material to the material outlet. An accurate metering volume     is discharged. The snuf back efect carried out   during the reilling, prevents the material from   dripping after metering is inished.
