16 Needle Ceramic Dispensing Valve
16 Needle Ceramic Dispensing sing Valve is a 16-pin hole design, advanced Ceramic material of high composition such as zirconia or alumina.It has good abrasion resistance, high hardness, high temperature resistance, non-stick and other properties.
16 Needle Ceramic Dispensing sing Valve is suitable for highly precise and repeatable applications.Depai quantitative valve has a variety of different series and sizes for customers to choose, a wide range of choices, in a variety of different industries in the application of quantitative processing, coating a variety of different materials, such as automotive parts on the glue, oil injection, or coated with silicone.
Ceramic Dispensing sing Valve has three different designs that can handle various Ceramic types of materials of varying viscosity from low to high, such as glue, sealant, grease, lubricating oil, silicone, etc.Ceramic Dispensing sing sing Valve is all pneumatic control, with the Ceramic Dispensing volume ranging from 0, 0.001ml to 100ml.In order to ensure that the material is accurately coated on the workpiece, a specially designed fixture will be equipped.
