DOSING VALVE DV25H
- DP-D-015-000021
- Dosing of low to high viscosity media
- Dosing range 0.02–2.5 cm³
- High reliability
- Low maintenance
- Long service life
Application
The DV25H is suitable for volumetric dosing of low to high viscosity media in the dosing range of 0.02–2.5 cm³ and can be used for manual as well as automatic dosing processes.
Description
The valve consists of two structurally separate parts. This design prevents uncontrolled leakage of the medium into the pneumatic cylinder and thus prevents interference with the valve needle.
The exact dosing quantity is set via the adjusting nuts with readable quantity scale, which enables repeatable, exact and precise dosing.
The metering cycle can be controlled pneumatically by means of a 5/2 directional control valve.
Advantages
The DV25H is characterized by high reliability and low maintenance.
The modular seal package ensures fast and service-friendly maintenance in just a few steps. The seals meet the latest technological standards and ensure a long service life for the valve.
