Benefits for you
Precise spray technology
With the volumetric spray valves, lubricants can be applied over surfaces and in small quantities with high repeat accuracy. The following versions are available:
- Needle metering valve (0.003 - 0.2 ml)
- Chamber metering valve (0.05 - 3 ml)
The perfect spray pattern for your part
Compared to conventional spray adapters, DOPAG valves are equipped with an integrated material throttle. The spray pattern can therefore be individually adjusted and splashes are avoided.
In addition, an almost unlimited selection of nozzle extensions is available to enable accessibility for all shapes and geometries. Depending on your requirements, we can also provide you with customised extensions.
Technical specifications:
- Volumetric metering for volumes from 0.003 - 3.00 ml
- Viscosity range 10 to 1,000,000 mPas
