The DV509 pneumatic diaphragm valve is suitable for medical applications that require precise flow control of low to medium-viscosity liquids such as cyanoacrylates, reagents, UV adhesives, and volatile substances where the wetted parts must be separated from the air supply. This valve can dispense >0.0001cc or 0.1µl at 200 cycles/sec. Use the VDP150 for constant high repeatability deposits of medium to high viscosity fluids of 5,000 to 20,000 cps. Shot size is tuned by a stroke adjuster in the valve. Filling a known chamber volume allows positive displacements down to 0.005cc or 5µl. A 4-way valve controller provides rapid cycling. And the PDV-1000 valve uses a series of precision screws for high-viscosity materials, 35,000cps and up. It makes repeatable deposits of >0.00003cc to 0.01µl. Shot-time intervals can range from 0.001 to 65.63 seconds. The PDV-1000 works with filled or abrasive materials.
