Dispensing Machine Dispensing Valve

Dispensing Machine Dispensing Valve is designed for Dispensing fluids and viscous media, especially for abrasive ones and those that are linear in flow and speed.Accuracy and repetition accuracy are plus or minus 1%.Dispensing Machine Dispensing Valve -- advanced ceramics.
Dispensing Machine Dispensing Valve is based on the volumetric principle of continuous screw movement; the main component, the rotor and stator, form a sealed, quantifiable cavity.

The eccentric motion of the rotor makes the medium move from one seal chamber to another in a low shear motion, which will not cause extrusion of the medium.The quantitative cavity is specially designed for conveying various common liquids and viscous liquids with fillers

Manufacturing precision:
Musashi ceramic dispensing valve precision machining dimension can be up to + / - 0.001mm, the minimum aperture can be machined 0.07mm, the minimum tolerance of the inner hole can be machined 0.005mm, the maximum cylindricity can be 0.004mm. High precision, high surface smoothness, good sealing performance completely changes the metal hard seal valve easy to leak, torque, sealing surface corrosion resistance shortcomings
