1. By material, Ceramic valve can be divided into Zirconia ceramic valve and Alumina ceramic valve.
2. By function and usage, Ceramic valve can be divided into Ceramic Dispensing Valve, Ceramic injection
pump and Ceramic Plunger Pump . Ceramic dispensing valve is applicable to Dispensing machine, having
the following good characteristics:
1) It produces the least backpressure and the smoothest liquid flow.
2) With the wear -resistant and high temperature-resistant properties, even under the high temperature
of 1400 °c, it can ensure the normal flow of liquid.
3) It can ensure that the liquid does not dry out in the valve.
The products are made of zirconia ceramic and alumina ceramic material, which have advanced
and excellent performances.
