PROPORTIONAL DOSING VALVE PDV04
- DP-D-005-000005
- Dosing range from 0.04 cm³
- Extremely process-safe dosing due to electronic monitoring
- Flexible, easily adjustable metering quantities and speeds
- Compact and space-saving design
- No pneumatic connection required
Application
The PDV04 enables uninterrupted dosing with freely selectable volumes from a quantity of 0.04 cm³ using the dosing principle with endless pistons.
Description
The PDV04 proportional dosing valve is an endless dosing valve and consists of an electrically driven piston metering unit.
The parameterization and control of the PDV04 is carried out via the control of the DS dosing system and thus enables continuous or clocked dosing. The standard interface to higher-level controls , e.g. for start or stop, is via digital I/Os. Further interfaces such as Profibus or Profinet are possible.
The compact and space-saving PDV04 proportional dosing system is designed for stationary as well as mobile use, e.g. on robots, and is connected to the D+P DS dosing system via a cable set of up to 20 meters in length.
Advantages
The PDV04 is viscosity-, pressure- and temperature-independent and ensures extremely process-safe metering thanks to electronic monitoring of the valve piston by means of an encoder. In addition, the PDV04 operates electromechanically and does not require a pneumatic connection.
The maintenance-friendly arrangement of the seal packs has also been implemented for the PDV04 in accordance with our new dosing valve series.
