970
Precision-design two-substance nozzle.
For laboratories, testing and small systems.
Model 970 is used for lots of trial applications, in laboratories and small production systems. The model series is manufactured using modular construction. This means that it can easily be converted into other designs. As a result, a wide range of applications are possible.
Based on viscosity, flow rate, density and surface tension, the series can be supplied in different versions.The series is equipped with an air cap with numerical scale. It enables the precision adjustment of the flow rate for the atomisation medium.
Model Highlights
For Industries and Applications
Available in various designs
Modular system
The model series is manufactured using modular construction. This means that it can easily be converted into other designs. As a result, a wide range of applications are possible.
Form 0
Basic model with blind plugs. To atomise liquids that are suctioned or supplied at a slight gradient. For even distribution on large, specific surfaces.
Form 3
With manual cleaning needle. Fast cleaning of the nozzle orifice during operation. To atomise sticky, unclean or highly viscous liquids.
Form 4
Design with a liquid quantity regulation needle. This design is particularly suitable for applications and atomisation tasks with highly variable flow rates.
Form 5
Like design 4, but with a highly precise scale at the liquid regulation needle for reproducible precision adjustment of the flow rate for trials, lab, etc.
Form 7
With pneumatic control through atomising air. The nozzle needle (also available as a cleaning needle) closes automatically and abruptly. Ideal for marking, signing and rhythmic spraying. No dripping.
Form 7-1
The same as form 7. However, the control takes place using control air via a separate connection. The atomising air does not need to be shut off. No dripping.
Form 8
With solenoid valve, normal version: 230 V, 50 Hz, 100% ED, max. 55°C ambient temperature, protection class: IP 65, cycling frequency: only limited by switchover time
