Dispensing Valves

Application of low to high viscosity media in a wide range of volumes

Dispensing valves by DOPAG are used in all industry sectors for discharging low to high-viscosity media. They feature high precision and very high repeatability with regard to discharge quantity. These valves are available in different series and design sizes. Due to the variety of valve types, there is a perfectly suitable valve for each individual application.

DOPAG produce a wide range of dispensing valves, used to apply many different single component materials, such as adhesives, sealants, greases and oils, fed under pressure from a pumping system. DOPAG dispensing valves are able to handle materials with viscosities up to 1,000,000 m Pas and will withstand pressures of between 150 and 250 bar, depending on the model chosen.
