Metering Valves
The precise DOPAG metering valves were designed for dot application of low- to high-viscosity media such as greases and oils. They are equally suitable for adhesives, sealants and silicones. The qualitative DOPAG metering valves have been used in all industrial sectors for decades. DOPAG metering valves meet all the requirements and standards that are important for optimum metering results, namely the highest precision and quality standards as well as very good reproducibility.
The DOPAG metering valves are based on the proven volumetric metering principle. During metering cycle an exact defined metering volume is discharged. The metering volume can be precisely adjusted by stop screw. Shot sizes between 0.001 ml and 100 ml are possible depending if a needle or chamber metering valve is used. The valves are easy to integrate in automated production lines. For manual application both valve types are available as handheld versions with an ergonomic design.
Different accessories like heating, pistol handles and hollow needles are available as accessories. For controlling and monitoring, solenoid valves, stroke detection and flow sensors are available as well, to guarantee highest process effectivity and reliability.

Chamber metering valves are used for dot application of low to high viscosity media. Compared to the needle metering valve, they offer a larger range of shot sizes. Thanks to an innovative design that features a snuff back effect, these valves are characteristic for their high process stability and dripfree application when dispensing low-viscosity media. The shot size is determined by the chamber volume, which can be adjusted simply within a predetermined range using a stop screw. The metering cycle is controlled either pneumatically or electrically via a solenoid valve. This valve series allows a highly repeatable metering of small quantities up to 100 ml within short cycle times. Manual application with a handle is just as possible as the integration into a fully automated process.

The volumetric spray valve combines the advantages of the volumetric metering principle with spray technology. Small spray patterns can be applied with maximum metering accuracy and reproducibility. High process stability is guaranteed at all times without material tempering or additional monitoring by means of a flow meter. The metering volume can be easily adjusted using the adjustment screw. A wide range of available extensions and attachments opens up the possibility of spraying in areas that are difficult to access, while various air caps allow the spray pattern to be customised.

Needle metering valves are suitable for dot application of low to high viscosity media. With this series, very small quantities of up to 3 ml per shot can be discharged with high reproducibility and short cycle times. The valve consists of two structurally separate parts, meaning that material cannot leak into the drive cylinder and interfere with the movement of the valve needle. This feature makes the needle metering valve an exceptionally reliable and low-maintenance piece of metering equipment. Shot size is determined by the volume of the valve chamber, which can be adjusted simply within a predetermined range using a stop screw. The metering cycle can be controlled either pneumatically or electrically via a solenoid valve. DOPAG needle metering valves are perfectly suitable for manual applications with a handle as well as for fully automated processes.
