Dispensing valves

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. These pneumatically actuated dispensing valves have a divorced design, separating the pneumatic actuator from the fluid section, thus eliminating the possibility of contamination from leakage.

Automatic and manual versions are available for each model of dispensing valve and manual versions can choose between pneumatically operated or electrically operated trigger mechanisms. Flow rates can easily be adjusted by means of a knurled wheel, which positions the needle in relation to the outlet seat of the dispensing valve.
