Dispensing valves

Application of low to high viscosity media in a wide range of volumes

Dispensing valves from DOPAG are used in all areas of industry for the application of low to high-viscosity media, such as lubricants, adhesives and sealants. This requires high precision and reproducibility. With numerous designs, series and sizes, the right valve can always be found for each individual application.

Depending on the requirement, the needle dispensing valve or diaphragm dispensing valve can be used for bead or dot application. This is a contact application, where the material bridges the gap between the valve needle and the component. For contactless application, or remote application of the material, DOPAG offers various valves such as the shot and spray valves. 

The dispensing valves are available in various forms. 

DOPAG dispensing valves can process materials with a viscosity of up to 1,000,000 m Pas depending on the version, at a pressure of 150-250 bar depending on the pump type. There are various drum and barrel pumps available for the material feed. In the case of dispensing valves, the volume is regulated via the material pressure and the opening time of the valve needle. Numerous components can be added to the system concept for testing and control, such as a gear flow rate measuring cell, a light barrier or a pressure sensor. All DOPAG valves can be integrated into fully automated production lines.
