Dispensing valves

For process-reliable metering of adhesives and lubricants

For continuous material application, you will find the right outlet valve for every application – regardless of whether you want to meter greases and oils or adhesives and sealants.

With the needle dispensing valve or the diaphragm dispensing valve, the material is continuously applied to the component as a dot or bead. The valves for contactless material application offer a wide range of options. They reliably apply lubricant from a distance to hard-to-reach and hidden places, for example as a shot or spray application.

Thanks to different series and sizes, you will always find the right valve for your application.

The right configuration for every application

Dispensing valves are metered according to the time-pressure principle. The metering quantity is set by the material pressure and the opening time of the valve needle. Thanks to their robust design, they can process materials with viscosities of up to 2,500,000 mPas.

Various drum and barrel pumps are available to supply the material. Various components can be added to the system concept for monitoring and control purposes – depending on the process safety requirements, for example, gear flow measuring cells, needle monitoring systems, photoelectric barriers or pressure sensors.

All dispensing valves can be integrated into fully automated production lines.
