8 Hole Ceramic Dispensing Valve
The ceramic dispensing valve is designed with a 8-hole design for a wide range of liquids and viscous media, especially for abrasive media and media with a linear relationship between flow and velocity.
The materials used can have zirconium oxide, alumina and other advanced ceramic materials. The ceramic dispensing valve enhanced nozzle design improves the uniformity of the spray pattern and is more accurate, with excellent edge clarity.
Its unique patented (QR) quick-disassembly clamp reduces downtime when maintaining a rubber valve to a few seconds.
Manufacturing precision:
Square 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. High precision, high surface smoothness, good sealing performance completely changes the metal hard seal Valve is easy to leak, torque is large, the lack of corrosion resistance on the sealing surface.
