Volume dosing valve for industrial, technical lubricants
The SOMA VDV – a reliable volume dosing valve from the dosing technology product range – enables lubricants to be dosed at a constant volume: in a volumetric and reproducible way and with process reliability.
The SOMA volume dosing valve (VDV) was developed for use in dosing processes where the dosing of precise volumes with repeat accuracy and contact is of paramount importance regardless of fluctuations in feed pressure and the viscosity of the lubricant being dosed.
The VDV is a modular valve in the shape of a cartridge, designed to dose low to high-viscosity media. It is used with a large range of lubricants, including solid lubricants.
The VDV can also be combined with different valve housings to form a dosing station with central medium supply.
Advantages of volume dosing valve
- Continuously adjustable, reproducible dosing volume
- Low medium upstream pressure to avoid lubricant segregation
- Can be combined with greasing tools in automated production systems
- Monitored material outlet for more safety
- Option of dosing solid lubricants
Areas of application
Would you like a little more? The SOMA VDV volume dosing valve showcases its strengths and benefits where greasing tools or contact applications are used in production. With its dosing volume of up to 235 mm³, the reliable volume dosing valve also supplies large-volume greasing systems with lubricant with repeat accuracy and precision.

SOMA dosing valves – the operating principle of the VDV
Dosing lubricants in a constant volume – this is how the SOMA VDV volume dosing valve works.
As a volume dosing unit, the SOMA VDV also has a continuously adjustable dosing chamber. A non-return poppet valve with back pressure relief, integrated in the output of the VDV dosing chamber, prevents the dosing medium from escaping in an uncontrolled manner up to a pressure of 6 bar.
The non-return valve, and also the dosing stroke, can be monitored by sensors, offering a solution with process reliability for dosing volumes of up to 235 mm³. Triggered by a 3/2-way pneumatic valve, it is able to dispense two full dosing volumes per second.
