Applications
  • Precise dispense of photoresist, adhesives, solvents and other media included in the molded version

Operations

  • Normally closed valve
  • Creates a vacuum when switching from open back to closed position to suck back a predetermined amount of liquid
  • Adjustment knob on top of valve gives excellent repeatability on the suckback volume

Features and Benefits

  • All virgin PTFE/high purity molded PFA wetted flow path
  • Eliminates dripping of media from nozzles after dispense cycle
  • Adjustable suckback capacity permits precise metering of media
  • Repeatability of suckback amount assures identical dispense volume for each cycle
  • Suitable for use with ultra high-purity or highly corrosive media
  • Innovative Furon SCR spring assures compatibility with HF and HC
  • Suitable for use in ozone applications (select models)

Notes

N/A
  • When selecting either Flare Grip® or Grab Seal™ ends, we recommend end connections that are larger than the valve orifice size in order to achieve full flow.
  • Adjusting to near zero suckback amount can cause the valve not to seal fully and leak across the valve seat.
  • The valve works best if the nozzle is placed no more than four feet (1.2 m) from the valve.
  • Leak detection port on side has standard port size of 1/4 - 28.
  • For applications in concentrated Hydrochloric (HCI) applications, please consult the factory.
