The VD520 Series dispense valves accurately control the application of most low to medium viscosity fluids without drips. The unique seal-less design incorporates an inert polymer diaphragm that isolates the actuator from the valve. The adjustable open/close stroke 0.13 to 0.64 mm (0.005" to 0.025") allows for a very fast response with positive shutoff.
Wetted components are made of inert plastic and stainless steel. Takes a direct feed from any pressure pot, cartridge or syringe and includes a selection of flexible fluid line tubing and connectors.
Valve open time can be as short as 15 milliseconds.
This version has a stainless steel fluid housing making it ideal for dispensing UV cure adhesives, lubricants and oils. Model VD520-SS with PTFE polymer and stainless steel wetted parts is used for dispensing solvents, gels, UV cure, liquids and glues. Simple to use with TS550R, TS250, TS350 digital timed controllers.
