Description of the alumina ceramic disc
Ceramic seal disc valving is an innovative liquid control system
found in the sanitary fitting, tap, faucet, regulator, diverter, water pump. Each time you use the devices, two
discs ( rotor and stator) control water, beverages, oil flow by
gliding back and forth in an airtight seal that prevents leaking
and ensures a super smooth operation.
The sliding surface of the ceramic sealing disk is extremely smooth
and almost as hard as diamonds. These durable valves are unaffected
by temperature extremes, sand, rust, and severe water conditions.
As ceramic seal 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.
Application of ceramic seal disc:
Ceramic seal discs are widely used in a variety of water faucet,
water tap, sanitary sealing system, regulating system, sealing
valves, water /oil/gas pump and so on.

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.
