PROPORTIONAL DOSING VALVE PDV03

DP-D-005-000003

Dosing range 0.01–0.5 cm³
No pneumatic connection needed
Extremely process-safe dosing due to electronic monitoring
Flexible, easily adjustable metering quantities and speeds
Independent of viscosity, pressure and temperature

Application

With the PDV03 proportional dosing valve, continuous as well as spot application of oils and greases up to a volume of 0.5 cm³ is possible.

Description

The PDV03 proportional dosing valve is a split system and has no integrated electronics. The resulting more compact size allows it to be mounted directly at the point of use. In addition, the PDV03 operates electromechanically and does not require a pneumatic connection.

The separate electronic control can be mounted flexibly with a permissible cable length of 3–20 meters.

The control takes place via the D+P dosing system DS.

Advantages

The freely selectable metering volume can be infinitely adjusted and applied at variable speed with pinpoint accuracy or over a wide area.

In the case of automated dispensing of several different positions on a workpiece, each position can be dispensed individually. This means that entire wetting profiles can be processed within one dispensing process.

The PDV03 is viscosity-, pressure- and temperature-independent and ensures extremely process-reliable metering thanks to electronic monitoring of the valve piston by means of an encoder.
