SlopeGate dispensing

Slider dispensing valve with "Slope-Gate" operation mode

short opening slider valve  for high frequency micro-dispensing and smallest dots of solid particle carrying fluids (solder 

paste, LED-materials,...)


Features and key benefits:
  1. bistabile slider mechanism for doubled dispensing speed
  2. smallest dot sizes for filled or paste like fluids achievable
  3. neither clogging nor welding of valve seats
  4. needle or contact dispensing
  5. optional: jet dispensing
  6. all wetted parts exchangeable
  7. full software control of dispensing process
  8. no dog bone or cobra head shape of dots or strings
  9. maximum accuracy and repeatability

paste, solderpaste, lubricants e.g. oils and grease, paints and

dyes, aqueous solutions,

organic solvents, adhesives and adhesive components, liquid polymers and polymer solutions, and many other liquids
