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,...)
- bistabile slider mechanism for doubled dispensing speed
- smallest dot sizes for filled or paste like fluids achievable
- 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
