2121 thimble dispensing valve belongs to the type of precision dispensing valve, which is inclined to small flow and high-precision dispensing demand. The axis adopts needle shape, which has good sealing effect. In the process of using low viscosity glue, there is still no glue leakage and wire drawing problem, which is suitable and convenient for daily dispensing demand.
  Working principle: the glue is delivered from the pressure barrel to the inside of the thimble type dispensing valve. Close the normally open air pressure, open the normally closed air pressure, the thimble will be folded up, and wait for the dispensing to be complete. The machine will control the dispensing controller to close the normally closed air pressure, and the axis will hold the sealing ring against it to prevent the glue from dropping. This is the whole working process of the thimble type dispensing valve.

Features of thimble dispensing valve:

1. The dispensing accuracy is high and has the effect of micro dispensing. The dispensing accuracy can also be adjusted according to the dispensing requirements.
2. It has the effect of back absorption, no drawing and leakage of glue, and the glue has the effect of back extraction. The glue at the glue outlet can be extracted back.
3. The rubber break is clean, the plunger axis is used, the sealing effect is good, similar to the dispensing of aqueous solution, still no leakage.
4. Long service life, made of stainless steel and aluminum alloy materials, aluminum alloy is anodized, with anti-corrosion effect.
5. Small size, easy to install, low requirement for machine use, can be used manually and automatically.
