Dispensing Valves


Diaphragm Valve

The VD510 is a diaphragm valve designed for precise flow control of low to medium viscosity materials.  The diaphragm separates the wetted parts from the moving parts and, therefore, the valve is ideal for dispensing cyanoacrylates, reagents, electrolytes, glues, solvents, paints, alcohol and other volatile substances.

3-Way Valve Operation
When air pressure is applied to the VD510 valve, the valve will open and the material will be dispensed. At the end of the dispense cycle a spring assists the diaphragm to return quickly to its closed state for immediate shut-off. Shot sizes may be fine tuned by turning the stroke adjustment at the top of the valve.


  • Stroke adjustment to fine tune shot size
  • Separated wetted parts
  • Suitable for robot integration
  • Suitable for anaerobic fluids
