Product Details

High Hardness Wear Resistance Aluminum Oxide / Alumina Ceramic Regulator Discs

Description of the ceramic regulator discs

Ceramic regulator discs are making from aluminum oxide ceramics (alumina) using a state-of-the-art method, which results in working surfaces with diamond-like hardness. The ceramic regulator discs also offer exceptional wear resistance, excellent chemical resistance against acids and alkaline solutions. The quality of the working surface ensures the superior reliability and long service life of ceramic sealing discs.

Even if the sand, rust are mixed in the valve, it will not impact the sealing performance. So even after 500,000 cycles, there are no signs of wear and continue to precisely control the desired amount of water in faucets and taps

As ceramic regulator disc is a key component in water, oil, gas sealing system, we always ensure that we manufacture best-quality products through strict quality control in every process, we introduced KPI into our manufacturing flow chart and keep all batches with consistent dimensions.

With over 15 years of manufacturing experience for ceramic seal discs, we have been supplying a variety of standard components, also we support various customized needs per your technical drawings, specification or practical samples.

If you are looking for a quality manufacturer for ceramic seal discs, please get through with us. We do believe you will find it's a wise choice.

Main characteristics of the ceramic regulator discs

1. Excellent wear-resistance and abrasion resistance, over 276 times than stainless steel

2. Exceptional hardness, the hardness is up to 1700MPa

3. Chemical stability, resistant most of strong acid and alkali

4. Perfect surface contact area ratio: the value can ensure between 60 ~ 80%

Packaging proposal and transportation solutions

1. We will keep the ceramic parts inside the inner package to be fixed without moving, then it will prevent them from collision each other, to avoid any cause any chippings during transportation.

2. In addition, the inside of the outer carton will be filled with sufficient protective kinds of stuff.
