Product information "Metering valve 0.003-0.2ml"
Needle metering valves are suitable for dot application of low to high viscosity media. With this series, very small quantities of up to 3 ml per shot can be discharged with high reproducibility and short cycle times. The valve consists of two structurally separate parts, meaning that material cannot leak into the drive cylinder and interfere with the movement of the valve needle. This feature makes the needle metering valve an exceptionally reliable and low-maintenance piece of metering equipment. Shot size is determined by the volume of the valve chamber, which can be adjusted simply within a predetermined range using a stop screw. The metering cycle can be controlled either pneumatically or electrically via a solenoid valve. DOPAG needle metering valves are perfectly suitable for manual applications with a handle as well as for fully automated processes.

MICRO-FLOW Sensor cpl.
Article number: 403.04.20
The micro-flow sensor detects whether material has been dispensed or not, without contact with the material. An analogue signal is amplified and forwarded to the electronic controller. The sensor is able to capture up to 120 metering cycles per minute. Should the electronic controller fail to send a signal as a result of no material flow, the master control unit will activate an alarm.

Article number: 1025106
The stroke detection device monitors the correct activity of various valve types. Detecting the upstroke movement of the dispensing needle or the metering piston, it sends signals to indicate the proper functioning of a valve.
