Slider dispensing valve
Slider dispensing valve
Slider valve for dispensing solid particle carrying fluids (solder paste, LED-materials,...)
Features and key benefits:
- slider mechanism allows dispensing suspended solids and paste
- dot and string dispensing for solid and abrasive loaded fluids
- neither clogging nor welding of valve seats
- needle or contact dispensing
- optional: jet dispensing
- all wetted parts exchangeable
- full software control of dispensing process
- no dog bone or cobra head shape of dots or strings
- maximum accuracy and repeatability
- lowest wear and tear of wetted parts
